<div>The '''[[Neo-Geo]]''' (ネオジオ) (officially printed as NEO•GEO) is a cartridge-based arcade and home video game system released on July 1, 1991 by Japanese game company SNK. Being in the Fourth generation of Gaming, it was the first console in the former Neo Geo family, which only lived through the 1990s. The hardware featured comparatively colourful 2D graphics. It's arcade counterpart is the [[Neo Geo MVS Arcade System]].<br />
<br />
The Neo Geo system was marketed as a very costly home console, commonly referred to today as the AES (Advanced Entertainment System). The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 16-bit system with an 8-bit Zilog Z80 as coprocessor. The coprocessor was used as a CPU, and for sound processing. The Super Nintendo and Sega Genesis also had similar co-processors, with neither Sega nor Nintendo claiming they were 24-bit.<br />
<br />
== History ==<br />
<br />
[[Image:Home_cart_system.jpg|300px|thumb|right]]<br />
<br />
Initially, the (AES) home system was only available for rent to commercial establishments, such as hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a $650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January, 1990 in Osaka, Japan. Compared to the other 16-bit consoles of the time, Neo Geo's graphics and sound were vastly superior. The MVS was one of the most powerful arcade units at the time. Furthermore, since the AES was identical to its arcade counterpart, the MVS, arcade titles released for the home market were perfect translations. Although its high price tag kept it out of the mainstream gaming market, a strong game lineup likely contributed to the cult status of the Neo Geo, enabling it to outlast the more popular Sega Mega Drive/Genesis.<br />
<br />
In the United States, the console was planned to debut at $599 USD and included two joystick controllers and a game, either Baseball Stars Professional or NAM-1975. However, the price was raised and its American launch debuted at $649.99. This package was known as the "Gold System." Later, the "Gold System" was bundled with Magician Lord and Fatal Fury. The system was also released in a "Silver System" package for $399.99, which included one joystick controller and did not include a game. Other games were priced at about $200 (and up). With these "premium" prices, though, most gamers weren't able to afford the system, so the console was only accessible to a niche market.<br />
<br />
The home system featured two CPUs: the 16-bit Motorola 68000 main processor running at 12 MHz and the 8-bit Zilog Z80 coprocessor running at 4 MHz. A custom video chipset allowed the system to display 4,096 colors and 380 individual sprites onscreen simultaneously, while the onboard Yamaha YM2610 sound chip gave the system 15 channels of sound with seven channels reserved specifically for digital sound effects. When realtime 3D graphics stormed the arcade industry, the Neo Geo's hardware was unable to follow along. The longevity of Neo Geo games kept it alive in arcades, particularly in Japan, where the newest installment of its flagship franchise, The King of Fighters, caused a stir with every new release.<br />
<br />
The last official game by SNK for the Neo Geo system, Samurai Shodown V Special, was released in 2004. SNK decided to abandon the video game hardware business due to the rampant piracy of game-cartridges, which SNK believed was partially responsible for its bankruptcy in 2001. SNK ceased to manufacture home consoles by the end of 1997, but continued to release games for both arcade and home for another 8 years.<br />
<br />
Measured from the introduction of the arcade hardware in 1990 to the release of the last official home cartridge in 2004, the Neo Geo enjoyed a market lifespan of fourteen years, making it the second longest-lived arcade or home console system ever produced (after Atari 2600). On August 31, 2007, SNK stopped offering maintenance and repairs to Neo Geo home consoles, handhelds, and games. However, they will continue to repair their MVS arcade hardware.<br />
<br />

<br />
== Technical Aspects ==<br />
<br />
Each joystick controller was 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × 2.5 in.) and contained the same four-button layout as the arcade MVS cabinet.<br />
<br />
The arcade machines had a memory card system by which a player could save a game to return to at a later time and could also be used to continue play on the SNK home console of the same name.<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial [[Homebrew]] games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />
=== Graphics ===<br />
<br />
Unlike most other video game consoles of its time, the Neo Geo did not use tilemap background layers. Instead, it relied exclusively on drawing sprites to create the background. Sprites are vertical strips which are 16 pixels wide, and can be 16 to 512 pixels tall. By laying multiple sprites side by side, the system can simulate a background layer. The system can draw up to 384 sprites on the screen at a time, and up to 96 per scanline.<br />

== Collecting ==<br />

<br />
=== Home Cartridges ===<br />
<br />
There is a thriving collector's scene for the Neo Geo home systems, especially the original AES home console. This is mainly because of the limited runs received by cartridges, the massive arcade library available, and the system's reputation as a 2D powerhouse. It is still common even to this day for both Neo Geo consoles and cartridges to fetch extremely high prices on eBay and other auction websites, particularly English versions of cartridges as these were produced in lower quantities. A handful of the rarest Neo Geo games can sell for well over $1,000 on eBay. This gives the system an almost cult following, as owners see the system as more of an "investment" rather than an ordinary videogame console. This leads to high resale value on most Neo Geo systems and games and makes the console a "must-have" for a number of video game collectors. The most expensive cartridge for the Neo Geo home system is the European-localized version of Kizuna Encounter: There are only five known copies of the game, with the most recently sold copy selling for about $12,000 USD.<br />
<br />
=== Conversions === <br />
<br />
[[Conversion]]s are NGH/AES cartridges that have had their original Mask ROMs removed and replaced with those of an MVS cartridge, typically from an MVS game which had a very limited and rare home cart release, or none at all. In a few cases, conversions are made with EPROMs instead of Mask ROMs. Those are more correctly labeled as bootlegs. Discussion is often a very touchy subject and thus information is not widely known on their creation. <br />
<br />
Generally, the value of a conversion is determined by the cost of parts (MVS cartridge, donor AES cart and label/insert) and not much more. Mask ROM conversions are usually worth only a fraction of an authentic NGH/AES copy. Ones made from EPROMs are worth considerably less. Conversions made from MVS exclusives are sometimes worth a bit more. <br />
<br />
In recent years, NGH/AES conversions have become increasingly advanced and near-identical to their authentic counterparts. So much that in some cases, the only way to distinguish between a conversion and an authentic copy is to have both on hand to meticulously compare. As a result the NGH/AES collector's market has become increasingly dangerous. Potential buyers are always highly encouraged to research a particular copy's history and integrity before they buy.<br />
<br />
On a related footnote, while often labeled as a stereotype, France has been accused and blamed for spearheading the advancement of conversions over the years. Some allegations against respected French collectors tend to be unfounded, while other cases have been proven with evidence.<br />
<br />
=== Freaked Cartridges=== <br />
<br />
A directly related subset of the home cartridges market, freaked cartridges are NGH/AES games that have been damaged in any number of ways by illegal distribution outfit Neo Geo Freak. The type of damage ranges from light cases of the occasional NGF sticker and re-printed case insert, to extreme examples of void stickers being plastered on the insert, cartridge and manual pages. The reasoning behind such damage isn't well known. <br />
<br />
In today's market, freaked cartridges are not very common and hardly change hands, likely from the drop in perceived value. Freaked carts with only a reprinted insert aren't worth much less than a legit copy, while horrifically freaked cartridges are always valued much less than pristine equivalents. <br />
<br />
== Modification ==<br />
<br />
[[Image:Modded_neo_geo2.jpg|300px|thumb|right|A Neo Geo console modded with Composite, S-Video, Component and Stereo Sound]]<br />
<br />
A popular facet of the Neo Geo that has grown over the years is the practice of modding NGH hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the Neo Geo. Commonly installed mods include: <br />
<br />
* S-Video (using the original Sony CXA1145 video encoder)<br />
* Component (using a new video encoder)<br />
* Universe BIOS (replacing the original stock BIOS<br />
* Debug BIOS (made obsolete by the Universe BIOS)<br />
* RGB Bypass (used to increase RGB video output fidelity)<br />
* Power LED (typically installed inside the reset button)<br />
* Replacement controller buttons/joystick (typically performed on Old Style sticks, sometimes HORI sticks)<br />
<br />
Most fan modding is done by individuals for their own personal use, though some people do it as a service. Popular service providers include:<br />
<br />
* Xian Xi (frequents Neo-Geo.com and runs Jamma Nation X)<br />
* JMKurtz <br />
* kpj (operates Neotropolis)<br />

* '''91)''' Some early US AES titles (like NAM-1975 and Magician Lord) were converted from Japanese, just by placing the US cartridge label over the JP one. <br />
* '''92)''' During the Mission 1 Boss fight in Metal Slug 2, a background banner in Arabic says "explosive diarrhea". <br />
<br />
<br />
<br />
And here's some things that couldn't easily be condensed into the list, or were too lacking in complete information: <br />
<br />
* In the NeoGeoCD version of SamShoII you can play as Kuroko (the referee-guy) by standing on some character, pressing up, down, up, down, left, right, left, right, blablabla or something. His weapon are the flags he always uses and he has a big fireball as in Art of Fighting style.<br />
<br />
* AOF 3 (i believe) has time release secrets/events. Something happens, I believe on Ryo's, Roberts, etc. birthdays. I'd find the thread, but the search is broken right now. <br />
<br />
* The only reason I was able to beat Sengoku 1 on AES was because of a ridiculous exploit trick I accidentally found: jumping constantly. If you get a up a power up ball, the new sword won't form in your hands till you stop jumping! So you get the most time out of every power up in the game because you chose when to activate the next one. <br />
<br />
* A BackGround Charecter in Metal Slug III is based on Ben Herman. <br />
<br />
* In Metal Slug X, if you use a debug BIOS, you can access "secret" incomplete-looking levels that appear to be level areas used in Metal Slug 3! You can wander around these levels and use vehicles such as a submarine and gyrocopter just like in MS3. If you were wondering why the meg count increased by over 100 between Metal Slug 2 and X, then this is your answer. There are also other debugging features that you can toggle on and off while exploring the areas. <br />
<br />
* in the King Of Fighters for the US Neo-Geo CD/home cart, Mai's boobies do not bouncy-bouncy. However, this "feature" was accessible with a code which was at the high score screen, press A and D on controller 1 simultaneously as you press B and C on controller 2, this code also made the blood appear.<br />
<br />
* In Neo Turf Masters, if you select the long hitter Mandel, there are several short cuts to albatrosses and even hole in ones. One such adventure is the Island shot on the Austrailian course. By hitting a full hard shot at the (lowest point) highest trajectory, the ball will bounce off the island and roll across the green nearest the pin. Your next shot will be for Albatross.. Oh yeah, practice makes perfect. If done just right the graphics get really strange. This is kinda like an Easter Egg Neo style. <br />
<br />
* In Pulstar, anyone ever notice how the default high scores are the chassis codes of Japanese cars?<br />
-R32 (Nissan Skyline R32)<br />
-Z32 (Nissan 300ZX Z32)<br />
-FD3 (Mazda RX7 FD3S)<br />
-JZA (Supra MkIII/IV JZA70/JZA80)<br />
-NSX (Honda/Acura NSX) <br />
<br />
<br />
* Did you know in Magical Drop 3 there are 6 secret characters that can be selected if you know the tarot card number of any of the characters? Just hit "C" 3 times while over the character whose number you know, when the timer reaches their number.<br />
<br />
20 - Judgment<br />
19 - Sun<br />
17 - Star<br />
15 - Devil<br />
13 - Death<br />
11 - Justice<br />
8 - Strength<br />
7 - Chariot<br />
6 - Lovers<br />
5 - Hierophant<br />
4 - Emperor<br />
3 - Empress<br />
2 - High Priestess<br />
1 - Magician<br />
0 - Fool<br />
<br />
Also Father Strength can be selected by selecting Strength by holding "C" and pressing "A & B" at the same time.<br />
<br />
<br />
* older NGH units have wrong values for the video circuitry in disregard of the values recommended by sony at the video encoder datasheet, this results in a darker picture, snk fixed the mistake at the later units and so they have a much brighter picture.<br />
<br />
The myth that the earlier units have better picture was caused by the latest and more common NGH revision the 3-6 which consists of half of the NGH systems ever made, it has a design problem at the video circuit that causes vertical lines when displaying RGB. It's easily fixed making it perform on par with board revision 3-5 which is the best stock unit as for RGB quality.<br />
<br />
The original and inconclusive research done by nfg, he had no access to most of the systems revisions, made wrong assumptions and didn't knew how to fix the RGB video problem at the 3-6 unit which caused striping.<br />
http://nfggames.com/games/neorgb2/<br />
<br />
MKL research on the matter, with access to all board revisions a conclusive explanation is offered, since the picture links are broken I'll post another link to the fix below.<br />

=== Bits on Pre-Neo Geo ===<br />
<br />
The Alpha68k (name from MAME) is more than likely an early version of the Neo Geo hardware. This can be verified by looking at the games in MAME. Alpha68k games are 256x224 using 2048 colors. The Neo Geo is 320x224 using 4096 colors.<br />
<br />
The flip bit for the sprites is bit 0 and 1 for Neo Geo, and bits 15 and 16 for the Alpha68k system. (Taken right from the MAME source).<br />
<br />
I've always wondered why they didn't have a tilemap like 99.99% of the other hardware of the time.<br />
I'm not sure about making programming easier (more flexible maybe), but the circuit design make sense. <br />
<br />
the Alpha68k, was used by Alpha Denshi as early at 1987, and SNK in 1988. SNK also started using the SNK68k system is 1988. The systems components and memory map are very close in design. Then there's the Beast Busters hardware, which isn't close to either, but does have the scaled sprites. Interesting is that the hardware components of the Neo Geo (12 Mhz 68000 4 Mhz Z80 YM2610 sound chip) more closely match the Beast Busters hardware than any other. There is almost no connection between this board and any of the others, though.<br />
<br />
SNK never designed the Neo Geo hardware system. Eiji Fukatsu himself designed it as an improved version of his 68K system. It features the essential sprite tiling system compressed into 3 chips, a scalar table in ROM function and a redone sound system as well as cartridge interface. <br />
<br />
=== Bits on the Corporate Neo Geo ===<br />
<br />
By Nightmare Tony: <br />
<br />
Kernow, Forever did remmeber right. If you have a schematic to any Neo geo system, it will have Alpha Denshi on it, along with their head wildman, Eiji Fukatsu. The system he actually did as a full board previously, first starting with a game called Battlefield (renamed to Time Soldiers). Romstar had the board redone also as Sky Soldiers and Gold Medalist. Sky Adventure also used the same system.<br />
<br />
As a general rule, graphic systems of the time used a background graphics, text and sprite graphics. Eiji instead used the sprites as tiles for the background, making programming and circuit design a tad simpler.<br />
<br />
The US president Marty was also an accomplished musician, magician and movie actor. Kept that to himself, though. Amazing talents.<br />
<br />
John Barone ended up marrying Susan Jarocki, who's dad Stan Jarocki ran this company called Bally-Midway. Games ran in that family, I guess.<br />
<br />
The tech department was an absolute blast. Between big band music, Rush Limbaugh, death metal and some absolutely wierd music, it was noisy and fun. For the entire US branch, though as Chad mentions, us being a broken arm, we did the best we could and had a lot of fun doing it.<br />
<br />
One competition which was a full tradition was a daily tech depamrtment competition of Thrash rally set up in 4 cabinets. I had my own cabinet modified with a steering wheel (showed at a trade show but no interest) which helped out immensely. The competition was quite insane and we all had a real good time.<br />
<br />
Romstar had been tied in with SNK back and forth, from being originally SNK USA to employees trading back and forth. At least 5 employees of Romstar (including yours truly) ended up at SNK at various times.<br />
<br />
Late night shipping runs included major pizza party action. We all worked like bulldogs and got the product out the door. When shipping time came round, RUSH was the order of the day.<br />
<br />
The Samurai Shodown trade advertisement with several people worshipping a cabinet with the "we're not worthy" included Game Lord, his sidekick George, some of the warehouse crew and the two sons of our graphics artist.<br />
<br />
The funniest program bomb I ever ran across personally was from a curious invention I was doing, to make a Neo Geo into a redemption game, giving out tickets. It had some good interest at the show and it earned like mad at the local test arcade. Then one morning, a bit of forgotten programming showed itself when the ticket photocell got dirty and gave out over 7,000 tickets. Whoops! (the program rewrite didnt finish as that is when the closure announcement came in). <br />
<br />
I had worked at Romstar previously, we had connectes with SNK. Back when the SNK home division was first started, Mr. Yasuki had sent me over to help solve some video output issues with the TV interface which was causing FCC failure problems. The solve was slightly detuning the crystal and the extra grounding wires to the crystal and area.<br />
<br />
Romstar had moved up North as Capcom was part owner and had it decided, and it was so. I was born and grew up in the LA area and did not want to move. It was a sad time, there were many tears. I wrote a sad poem about it all in rememberance. I will post it.<br />
<br />
Mr. Yasuki pulled strings and got me into SNK which was in a bigger building doing arcade. At Romstar, we had licensed the 1 slot system for sale as a conversion kit. I still remember the first 10,000 boards came in, a HUGE stack of boxes, maybe 40 feet deep, 10 feet tall, 10-20 feet wide. Took up a LOT of the warehouse.<br />
<br />
Romstar was quite mellow and an adventure. Had it stayed, I would have had my first inhouse 100% programmed game within a year, I was helping develop the Terra 2 arcade system there. It was 286 based with CPLD graphic chip systems to allow the graphicvs path to be revised. I do have the board layout somewhere, I will have to post it someday. The main board was designed by Doug Hughes, who designed the hardware system used by Taito for the game Qix (an entirely American game with no Japanes programming or design whatsoever).<br />
<br />
SNK seemed tougher at first but I got the rhythmn. We all had a lot of fun and creativity ran well. For breaks, we all competed in darts and Thrash Rally 2 times a day. I had designed a steering wheel control panel and pedal and it kept me int he race since I usually suck at games, and I Was able to keep up. The Thrash contests were on 4 cabinets, and we were SAVAGE players. Plenty of smack talk aqnd competition.<br />
<br />
I did the arcade repairs, answered phones and tech department things. I also did design work and odd things.<br />
<br />
SNK went up north due to the Neo Print, I got a job as a distributor. Ended up hating that job since it became a Dilbert cartoon come to life. Ironically, the home division guy at SNK is working there at that same distributor right now.<br />
<br />
My present job is engineering, doing circuit board design of phone and security system entry ways. VERY fun job.<br />
<br />
Anyhoo, that is why I still remember my neo tech stuph. But yup, it was a job that stood out. Lots of fun. The only reason I give it a 2-3% less than Romstar and present job, it seemed a tiny bit stiff at first, but once I got the hang and rhythmn, it all worked out. Personal wise, we were great, did Christmas walks together, partied together. Was very much a family.</div>HeavyMachineGunhttps://www.neo-geo.com/wiki/index.php?title=Neo_Geo_MVS_Arcade_System&diff=4326Neo Geo MVS Arcade System2012-03-19T21:45:10Z<p>HeavyMachineGun: /* Other */</p>

<br />
The '''[[MVS]]''' (Multi Video System), as the [[Neo-Geo]] was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-[[slot]], 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />

<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
[[Image:Bootleg_neo_geo_cup_98_prg.jpg|300px|thumb|An example of a bootleg MVS game]]<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies.<br />

<br />
== Modification ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:cmvsomega.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

<br />
The '''[[MVS]]''' (Multi Video System), as the [[Neo-Geo]] was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-[[slot]], 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />

<br />
<br />
<br />
And here's some things that couldn't easily be condensed into the list, or were too lacking in complete information: <br />
<br />
* In the NeoGeoCD version of SamShoII you can play as Kuroko (the referee-guy) by standing on some character, pressing up, down, up, down, left, right, left, right, blablabla or something. His weapon are the flags he always uses and he has a big fireball as in Art of Fighting style.<br />
<br />
* AOF 3 (i believe) has time release secrets/events. Something happens, I believe on Ryo's, Roberts, etc. birthdays. I'd find the thread, but the search is broken right now. <br />
<br />
* The only reason I was able to beat Sengoku 1 on AES was because of a ridiculous exploit trick I accidentally found: jumping constantly. If you get a up a power up ball, the new sword won't form in your hands till you stop jumping! So you get the most time out of every power up in the game because you chose when to activate the next one. <br />
<br />
* A BackGround Charecter in Metal Slug III is based on Ben Herman. <br />
<br />
* In Metal Slug X, if you use a debug BIOS, you can access "secret" incomplete-looking levels that appear to be level areas used in Metal Slug 3! You can wander around these levels and use vehicles such as a submarine and gyrocopter just like in MS3. If you were wondering why the meg count increased by over 100 between Metal Slug 2 and X, then this is your answer. There are also other debugging features that you can toggle on and off while exploring the areas. <br />
<br />
* in the King Of Fighters for the US Neo-Geo CD/home cart, Mai's boobies do not bouncy-bouncy. However, this "feature" was accessible with a code which was at the high score screen, press A and D on controller 1 simultaneously as you press B and C on controller 2, this code also made the blood appear.<br />
<br />
* In Neo Turf Masters, if you select the long hitter Mandel, there are several short cuts to albatrosses and even hole in ones. One such adventure is the Island shot on the Austrailian course. By hitting a full hard shot at the (lowest point) highest trajectory, the ball will bounce off the island and roll across the green nearest the pin. Your next shot will be for Albatross.. Oh yeah, practice makes perfect. If done just right the graphics get really strange. This is kinda like an Easter Egg Neo style. <br />
<br />
* In Pulstar, anyone ever notice how the default high scores are the chassis codes of Japanese cars?<br />
-R32 (Nissan Skyline R32)<br />
-Z32 (Nissan 300ZX Z32)<br />
-FD3 (Mazda RX7 FD3S)<br />
-JZA (Supra MkIII/IV JZA70/JZA80)<br />
-NSX (Honda/Acura NSX) <br />
<br />
<br />
* Did you know in Magical Drop 3 there are 6 secret characters that can be selected if you know the tarot card number of any of the characters? Just hit "C" 3 times while over the character whose number you know, when the timer reaches their number.<br />
<br />
20 - Judgment<br />
19 - Sun<br />
17 - Star<br />
15 - Devil<br />
13 - Death<br />
11 - Justice<br />
8 - Strength<br />
7 - Chariot<br />
6 - Lovers<br />
5 - Hierophant<br />
4 - Emperor<br />
3 - Empress<br />
2 - High Priestess<br />
1 - Magician<br />
0 - Fool<br />
<br />
Also Father Strength can be selected by selecting Strength by holding "C" and pressing "A & B" at the same time.<br />
<br />
<br />
* older NGH units have wrong values for the video circuitry in disregard of the values recommended by sony at the video encoder datasheet, this results in a darker picture, snk fixed the mistake at the later units and so they have a much brighter picture.<br />
<br />
The myth that the earlier units have better picture was caused by the latest and more common NGH revision the 3-6 which consists of half of the NGH systems ever made, it has a design problem at the video circuit that causes vertical lines when displaying RGB. It's easily fixed making it perform on par with board revision 3-5 which is the best stock unit as for RGB quality.<br />
<br />
The original and inconclusive research done by nfg, he had no access to most of the systems revisions, made wrong assumptions and didn't knew how to fix the RGB video problem at the 3-6 unit which caused striping.<br />
http://nfggames.com/games/neorgb2/<br />
<br />
MKL research on the matter, with access to all board revisions a conclusive explanation is offered, since the picture links are broken I'll post another link to the fix below.<br />

=== Bits on Pre-Neo Geo ===<br />
<br />
The Alpha68k (name from MAME) is more than likely an early version of the Neo Geo hardware. This can be verified by looking at the games in MAME. Alpha68k games are 256x224 using 2048 colors. The Neo Geo is 320x224 using 4096 colors.<br />
<br />
The flip bit for the sprites is bit 0 and 1 for Neo Geo, and bits 15 and 16 for the Alpha68k system. (Taken right from the MAME source).<br />
<br />
I've always wondered why they didn't have a tilemap like 99.99% of the other hardware of the time.<br />
I'm not sure about making programming easier (more flexible maybe), but the circuit design make sense. <br />
<br />
the Alpha68k, was used by Alpha Denshi as early at 1987, and SNK in 1988. SNK also started using the SNK68k system is 1988. The systems components and memory map are very close in design. Then there's the Beast Busters hardware, which isn't close to either, but does have the scaled sprites. Interesting is that the hardware components of the Neo Geo (12 Mhz 68000 4 Mhz Z80 YM2610 sound chip) more closely match the Beast Busters hardware than any other. There is almost no connection between this board and any of the others, though.<br />
<br />
SNK never designed the Neo Geo hardware system. Eiji Fukatsu himself designed it as an improved version of his 68K system. It features the essential sprite tiling system compressed into 3 chips, a scalar table in ROM function and a redone sound system as well as cartridge interface. <br />
<br />
=== Bits on the Corporate Neo Geo ===<br />
<br />
By Nightmare Tony: <br />
<br />
Kernow, Forever did remmeber right. If you have a schematic to any Neo geo system, it will have Alpha Denshi on it, along with their head wildman, Eiji Fukatsu. The system he actually did as a full board previously, first starting with a game called Battlefield (renamed to Time Soldiers). Romstar had the board redone also as Sky Soldiers and Gold Medalist. Sky Adventure also used the same system.<br />
<br />
As a general rule, graphic systems of the time used a background graphics, text and sprite graphics. Eiji instead used the sprites as tiles for the background, making programming and circuit design a tad simpler.<br />
<br />
The US president Marty was also an accomplished musician, magician and movie actor. Kept that to himself, though. Amazing talents.<br />
<br />
John Barone ended up marrying Susan Jarocki, who's dad Stan Jarocki ran this company called Bally-Midway. Games ran in that family, I guess.<br />
<br />
The tech department was an absolute blast. Between big band music, Rush Limbaugh, death metal and some absolutely wierd music, it was noisy and fun. For the entire US branch, though as Chad mentions, us being a broken arm, we did the best we could and had a lot of fun doing it.<br />
<br />
One competition which was a full tradition was a daily tech depamrtment competition of Thrash rally set up in 4 cabinets. I had my own cabinet modified with a steering wheel (showed at a trade show but no interest) which helped out immensely. The competition was quite insane and we all had a real good time.<br />
<br />
Romstar had been tied in with SNK back and forth, from being originally SNK USA to employees trading back and forth. At least 5 employees of Romstar (including yours truly) ended up at SNK at various times.<br />
<br />
Late night shipping runs included major pizza party action. We all worked like bulldogs and got the product out the door. When shipping time came round, RUSH was the order of the day.<br />
<br />
The Samurai Shodown trade advertisement with several people worshipping a cabinet with the "we're not worthy" included Game Lord, his sidekick George, some of the warehouse crew and the two sons of our graphics artist.<br />
<br />
The funniest program bomb I ever ran across personally was from a curious invention I was doing, to make a Neo Geo into a redemption game, giving out tickets. It had some good interest at the show and it earned like mad at the local test arcade. Then one morning, a bit of forgotten programming showed itself when the ticket photocell got dirty and gave out over 7,000 tickets. Whoops! (the program rewrite didnt finish as that is when the closure announcement came in). <br />
<br />
I had worked at Romstar previously, we had connectes with SNK. Back when the SNK home division was first started, Mr. Yasuki had sent me over to help solve some video output issues with the TV interface which was causing FCC failure problems. The solve was slightly detuning the crystal and the extra grounding wires to the crystal and area.<br />
<br />
Romstar had moved up North as Capcom was part owner and had it decided, and it was so. I was born and grew up in the LA area and did not want to move. It was a sad time, there were many tears. I wrote a sad poem about it all in rememberance. I will post it.<br />
<br />
Mr. Yasuki pulled strings and got me into SNK which was in a bigger building doing arcade. At Romstar, we had licensed the 1 slot system for sale as a conversion kit. I still remember the first 10,000 boards came in, a HUGE stack of boxes, maybe 40 feet deep, 10 feet tall, 10-20 feet wide. Took up a LOT of the warehouse.<br />
<br />
Romstar was quite mellow and an adventure. Had it stayed, I would have had my first inhouse 100% programmed game within a year, I was helping develop the Terra 2 arcade system there. It was 286 based with CPLD graphic chip systems to allow the graphicvs path to be revised. I do have the board layout somewhere, I will have to post it someday. The main board was designed by Doug Hughes, who designed the hardware system used by Taito for the game Qix (an entirely American game with no Japanes programming or design whatsoever).<br />
<br />
SNK seemed tougher at first but I got the rhythmn. We all had a lot of fun and creativity ran well. For breaks, we all competed in darts and Thrash Rally 2 times a day. I had designed a steering wheel control panel and pedal and it kept me int he race since I usually suck at games, and I Was able to keep up. The Thrash contests were on 4 cabinets, and we were SAVAGE players. Plenty of smack talk aqnd competition.<br />
<br />
I did the arcade repairs, answered phones and tech department things. I also did design work and odd things.<br />
<br />
SNK went up north due to the Neo Print, I got a job as a distributor. Ended up hating that job since it became a Dilbert cartoon come to life. Ironically, the home division guy at SNK is working there at that same distributor right now.<br />
<br />
My present job is engineering, doing circuit board design of phone and security system entry ways. VERY fun job.<br />
<br />
Anyhoo, that is why I still remember my neo tech stuph. But yup, it was a job that stood out. Lots of fun. The only reason I give it a 2-3% less than Romstar and present job, it seemed a tiny bit stiff at first, but once I got the hang and rhythmn, it all worked out. Personal wise, we were great, did Christmas walks together, partied together. Was very much a family.</div>HeavyMachineGunhttps://www.neo-geo.com/wiki/index.php?title=Things_You_Never_Knew_About_the_Neo_Geo&diff=4313Things You Never Knew About the Neo Geo2012-03-15T19:30:01Z<p>HeavyMachineGun: </p>

<br />
<br />
<br />
And here's some things that couldn't easily be condensed into the list, or were too lacking in complete information: <br />
<br />
* In the NeoGeoCD version of SamShoII you can play as Kuroko (the referee-guy) by standing on some character, pressing up, down, up, down, left, right, left, right, blablabla or something. His weapon are the flags he always uses and he has a big fireball as in Art of Fighting style.<br />
<br />
* AOF 3 (i believe) has time release secrets/events. Something happens, I believe on Ryo's, Roberts, etc. birthdays. I'd find the thread, but the search is broken right now. <br />
<br />
* The only reason I was able to beat Sengoku 1 on AES was because of a ridiculous exploit trick I accidentally found: jumping constantly. If you get a up a power up ball, the new sword won't form in your hands till you stop jumping! So you get the most time out of every power up in the game because you chose when to activate the next one. <br />
<br />
* A BackGround Charecter in Metal Slug III is based on Ben Herman. <br />
<br />
* In Metal Slug X, if you use a debug BIOS, you can access "secret" incomplete-looking levels that appear to be level areas used in Metal Slug 3! You can wander around these levels and use vehicles such as a submarine and gyrocopter just like in MS3. If you were wondering why the meg count increased by over 100 between Metal Slug 2 and X, then this is your answer. There are also other debugging features that you can toggle on and off while exploring the areas. <br />
<br />
* in the King Of Fighters for the US Neo-Geo CD/home cart, Mai's boobies do not bouncy-bouncy. However, this "feature" was accessible with a code which was at the high score screen, press A and D on controller 1 simultaneously as you press B and C on controller 2, this code also made the blood appear.<br />
<br />
* In Neo Turf Masters, if you select the long hitter Mandel, there are several short cuts to albatrosses and even hole in ones. One such adventure is the Island shot on the Austrailian course. By hitting a full hard shot at the (lowest point) highest trajectory, the ball will bounce off the island and roll across the green nearest the pin. Your next shot will be for Albatross.. Oh yeah, practice makes perfect. If done just right the graphics get really strange. This is kinda like an Easter Egg Neo style. <br />
<br />
* In Pulstar, anyone ever notice how the default high scores are the chassis codes of Japanese cars?<br />
-R32 (Nissan Skyline R32)<br />
-Z32 (Nissan 300ZX Z32)<br />
-FD3 (Mazda RX7 FD3S)<br />
-JZA (Supra MkIII/IV JZA70/JZA80)<br />
-NSX (Honda/Acura NSX) <br />
<br />
<br />
* Did you know in Magical Drop 3 there are 6 secret characters that can be selected if you know the tarot card number of any of the characters? Just hit "C" 3 times while over the character whose number you know, when the timer reaches their number.<br />
<br />
20 - Judgment<br />
19 - Sun<br />
17 - Star<br />
15 - Devil<br />
13 - Death<br />
11 - Justice<br />
8 - Strength<br />
7 - Chariot<br />
6 - Lovers<br />
5 - Hierophant<br />
4 - Emperor<br />
3 - Empress<br />
2 - High Priestess<br />
1 - Magician<br />
0 - Fool<br />
<br />
Also Father Strength can be selected by selecting Strength by holding "C" and pressing "A & B" at the same time.<br />
<br />
<br />
* older NGH units have wrong values for the video circuitry in disregard of the values recommended by sony at the video encoder datasheet, this results in a darker picture, snk fixed the mistake at the later units and so they have a much brighter picture.<br />
<br />
The myth that the earlier units have better picture was caused by the latest and more common NGH revision the 3-6 which consists of half of the NGH systems ever made, it has a design problem at the video circuit that causes vertical lines when displaying RGB. It's easily fixed making it perform on par with board revision 3-5 which is the best stock unit as for RGB quality.<br />
<br />
The original and inconclusive research done by nfg, he had no access to most of the systems revisions, made wrong assumptions and didn't knew how to fix the RGB video problem at the 3-6 unit which caused striping.<br />
http://nfggames.com/games/neorgb2/<br />
<br />
MKL research on the matter, with access to all board revisions a conclusive explanation is offered, since the picture links are broken I'll post another link to the fix below.<br />

=== Bits on Pre-Neo Geo ===<br />
<br />
The Alpha68k (name from MAME) is more than likely an early version of the Neo Geo hardware. This can be verified by looking at the games in MAME. Alpha68k games are 256x224 using 2048 colors. The Neo Geo is 320x224 using 4096 colors.<br />
<br />
The flip bit for the sprites is bit 0 and 1 for Neo Geo, and bits 15 and 16 for the Alpha68k system. (Taken right from the MAME source).<br />
<br />
I've always wondered why they didn't have a tilemap like 99.99% of the other hardware of the time.<br />
I'm not sure about making programming easier (more flexible maybe), but the circuit design make sense. <br />
<br />
the Alpha68k, was used by Alpha Denshi as early at 1987, and SNK in 1988. SNK also started using the SNK68k system is 1988. The systems components and memory map are very close in design. Then there's the Beast Busters hardware, which isn't close to either, but does have the scaled sprites. Interesting is that the hardware components of the Neo Geo (12 Mhz 68000 4 Mhz Z80 YM2610 sound chip) more closely match the Beast Busters hardware than any other. There is almost no connection between this board and any of the others, though.<br />
<br />
SNK never designed the Neo Geo hardware system. Eiji Fukatsu himself designed it as an improved version of his 68K system. It features the essential sprite tiling system compressed into 3 chips, a scalar table in ROM function and a redone sound system as well as cartridge interface. <br />
<br />
=== Bits on the Corporate Neo Geo ===<br />
<br />
By Nightmare Tony: <br />
<br />
Kernow, Forever did remmeber right. If you have a schematic to any Neo geo system, it will have Alpha Denshi on it, along with their head wildman, Eiji Fukatsu. The system he actually did as a full board previously, first starting with a game called Battlefield (renamed to Time Soldiers). Romstar had the board redone also as Sky Soldiers and Gold Medalist. Sky Adventure also used the same system.<br />
<br />
As a general rule, graphic systems of the time used a background graphics, text and sprite graphics. Eiji instead used the sprites as tiles for the background, making programming and circuit design a tad simpler.<br />
<br />
The US president Marty was also an accomplished musician, magician and movie actor. Kept that to himself, though. Amazing talents.<br />
<br />
John Barone ended up marrying Susan Jarocki, who's dad Stan Jarocki ran this company called Bally-Midway. Games ran in that family, I guess.<br />
<br />
The tech department was an absolute blast. Between big band music, Rush Limbaugh, death metal and some absolutely wierd music, it was noisy and fun. For the entire US branch, though as Chad mentions, us being a broken arm, we did the best we could and had a lot of fun doing it.<br />
<br />
One competition which was a full tradition was a daily tech depamrtment competition of Thrash rally set up in 4 cabinets. I had my own cabinet modified with a steering wheel (showed at a trade show but no interest) which helped out immensely. The competition was quite insane and we all had a real good time.<br />
<br />
Romstar had been tied in with SNK back and forth, from being originally SNK USA to employees trading back and forth. At least 5 employees of Romstar (including yours truly) ended up at SNK at various times.<br />
<br />
Late night shipping runs included major pizza party action. We all worked like bulldogs and got the product out the door. When shipping time came round, RUSH was the order of the day.<br />
<br />
The Samurai Shodown trade advertisement with several people worshipping a cabinet with the "we're not worthy" included Game Lord, his sidekick George, some of the warehouse crew and the two sons of our graphics artist.<br />
<br />
The funniest program bomb I ever ran across personally was from a curious invention I was doing, to make a Neo Geo into a redemption game, giving out tickets. It had some good interest at the show and it earned like mad at the local test arcade. Then one morning, a bit of forgotten programming showed itself when the ticket photocell got dirty and gave out over 7,000 tickets. Whoops! (the program rewrite didnt finish as that is when the closure announcement came in). <br />
<br />
I had worked at Romstar previously, we had connectes with SNK. Back when the SNK home division was first started, Mr. Yasuki had sent me over to help solve some video output issues with the TV interface which was causing FCC failure problems. The solve was slightly detuning the crystal and the extra grounding wires to the crystal and area.<br />
<br />
Romstar had moved up North as Capcom was part owner and had it decided, and it was so. I was born and grew up in the LA area and did not want to move. It was a sad time, there were many tears. I wrote a sad poem about it all in rememberance. I will post it.<br />
<br />
Mr. Yasuki pulled strings and got me into SNK which was in a bigger building doing arcade. At Romstar, we had licensed the 1 slot system for sale as a conversion kit. I still remember the first 10,000 boards came in, a HUGE stack of boxes, maybe 40 feet deep, 10 feet tall, 10-20 feet wide. Took up a LOT of the warehouse.<br />
<br />
Romstar was quite mellow and an adventure. Had it stayed, I would have had my first inhouse 100% programmed game within a year, I was helping develop the Terra 2 arcade system there. It was 286 based with CPLD graphic chip systems to allow the graphicvs path to be revised. I do have the board layout somewhere, I will have to post it someday. The main board was designed by Doug Hughes, who designed the hardware system used by Taito for the game Qix (an entirely American game with no Japanes programming or design whatsoever).<br />
<br />
SNK seemed tougher at first but I got the rhythmn. We all had a lot of fun and creativity ran well. For breaks, we all competed in darts and Thrash Rally 2 times a day. I had designed a steering wheel control panel and pedal and it kept me int he race since I usually suck at games, and I Was able to keep up. The Thrash contests were on 4 cabinets, and we were SAVAGE players. Plenty of smack talk aqnd competition.<br />
<br />
I did the arcade repairs, answered phones and tech department things. I also did design work and odd things.<br />
<br />
SNK went up north due to the Neo Print, I got a job as a distributor. Ended up hating that job since it became a Dilbert cartoon come to life. Ironically, the home division guy at SNK is working there at that same distributor right now.<br />
<br />
My present job is engineering, doing circuit board design of phone and security system entry ways. VERY fun job.<br />
<br />
Anyhoo, that is why I still remember my neo tech stuph. But yup, it was a job that stood out. Lots of fun. The only reason I give it a 2-3% less than Romstar and present job, it seemed a tiny bit stiff at first, but once I got the hang and rhythmn, it all worked out. Personal wise, we were great, did Christmas walks together, partied together. Was very much a family.</div>HeavyMachineGunhttps://www.neo-geo.com/wiki/index.php?title=Things_You_Never_Knew_About_the_Neo_Geo&diff=4309Things You Never Knew About the Neo Geo2012-02-15T22:48:32Z<p>HeavyMachineGun: </p>

<br />
<br />
And here's some things that couldn't easily be condensed into the list, or were too lacking in complete information: <br />
<br />
* In the NeoGeoCD version of SamShoII you can play as Kuroko (the referee-guy) by standing on some character, pressing up, down, up, down, left, right, left, right, blablabla or something. His weapon are the flags he always uses and he has a big fireball as in Art of Fighting style.<br />
<br />
* AOF 3 (i believe) has time release secrets/events. Something happens, I believe on Ryo's, Roberts, etc. birthdays. I'd find the thread, but the search is broken right now. <br />
<br />
* The only reason I was able to beat Sengoku 1 on AES was because of a ridiculous exploit trick I accidentally found: jumping constantly. If you get a up a power up ball, the new sword won't form in your hands till you stop jumping! So you get the most time out of every power up in the game because you chose when to activate the next one. <br />
<br />
* A BackGround Charecter in Metal Slug III is based on Ben Herman. <br />
<br />
* In Metal Slug X, if you use a debug BIOS, you can access "secret" incomplete-looking levels that appear to be level areas used in Metal Slug 3! You can wander around these levels and use vehicles such as a submarine and gyrocopter just like in MS3. If you were wondering why the meg count increased by over 100 between Metal Slug 2 and X, then this is your answer. There are also other debugging features that you can toggle on and off while exploring the areas. <br />
<br />
* in the King Of Fighters for the US Neo-Geo CD/home cart, Mai's boobies do not bouncy-bouncy. However, this "feature" was accessible with a code which was at the high score screen, press A and D on controller 1 simultaneously as you press B and C on controller 2, this code also made the blood appear.<br />
<br />
* In Neo Turf Masters, if you select the long hitter Mandel, there are several short cuts to albatrosses and even hole in ones. One such adventure is the Island shot on the Austrailian course. By hitting a full hard shot at the (lowest point) highest trajectory, the ball will bounce off the island and roll across the green nearest the pin. Your next shot will be for Albatross.. Oh yeah, practice makes perfect. If done just right the graphics get really strange. This is kinda like an Easter Egg Neo style. <br />
<br />
* In Pulstar, anyone ever notice how the default high scores are the chassis codes of Japanese cars?<br />
-R32 (Nissan Skyline R32)<br />
-Z32 (Nissan 300ZX Z32)<br />
-FD3 (Mazda RX7 FD3S)<br />
-JZA (Supra MkIII/IV JZA70/JZA80)<br />
-NSX (Honda/Acura NSX) <br />
<br />
<br />
* Did you know in Magical Drop 3 there are 6 secret characters that can be selected if you know the tarot card number of any of the characters? Just hit "C" 3 times while over the character whose number you know, when the timer reaches their number.<br />
<br />
20 - Judgment<br />
19 - Sun<br />
17 - Star<br />
15 - Devil<br />

<br />
* older NGH units have wrong values for the video circuitry in disregard of the values recommended by sony at the video encoder datasheet, this results in a darker picture, snk fixed the mistake at the later units and so they have a much brighter picture.<br />
<br />
The myth that the earlier units have better picture was caused by the latest and more common NGH revision the 3-6 which consists of half of the NGH systems ever made, it has a design problem at the video circuit that causes vertical lines when displaying RGB. It's easily fixed making it perform on par with board revision 3-5 which is the best stock unit as for RGB quality.<br />
<br />
The original and inconclusive research done by nfg, he had no access to most of the systems revisions, made wrong assumptions and didn't knew how to fix the RGB video problem at the 3-6 unit which caused striping.<br />
http://nfggames.com/games/neorgb2/<br />
<br />
MKL research on the matter, with access to all board revisions a conclusive explanation is offered, since the picture links are broken I'll post another link to the fix below.<br />

=== Bits on Pre-Neo Geo ===<br />
<br />
The Alpha68k (name from MAME) is more than likely an early version of the Neo Geo hardware. This can be verified by looking at the games in MAME. Alpha68k games are 256x224 using 2048 colors. The Neo Geo is 320x224 using 4096 colors.<br />
<br />
The flip bit for the sprites is bit 0 and 1 for Neo Geo, and bits 15 and 16 for the Alpha68k system. (Taken right from the MAME source).<br />
<br />
I've always wondered why they didn't have a tilemap like 99.99% of the other hardware of the time.<br />
I'm not sure about making programming easier (more flexible maybe), but the circuit design make sense. <br />
<br />
the Alpha68k, was used by Alpha Denshi as early at 1987, and SNK in 1988. SNK also started using the SNK68k system is 1988. The systems components and memory map are very close in design. Then there's the Beast Busters hardware, which isn't close to either, but does have the scaled sprites. Interesting is that the hardware components of the Neo Geo (12 Mhz 68000 4 Mhz Z80 YM2610 sound chip) more closely match the Beast Busters hardware than any other. There is almost no connection between this board and any of the others, though.<br />
<br />
SNK never designed the Neo Geo hardware system. Eiji Fukatsu himself designed it as an improved version of his 68K system. It features the essential sprite tiling system compressed into 3 chips, a scalar table in ROM function and a redone sound system as well as cartridge interface. <br />
<br />
=== Bits on the Corporate Neo Geo ===<br />
<br />
By Nightmare Tony: <br />
<br />
Kernow, Forever did remmeber right. If you have a schematic to any Neo geo system, it will have Alpha Denshi on it, along with their head wildman, Eiji Fukatsu. The system he actually did as a full board previously, first starting with a game called Battlefield (renamed to Time Soldiers). Romstar had the board redone also as Sky Soldiers and Gold Medalist. Sky Adventure also used the same system.<br />
<br />
As a general rule, graphic systems of the time used a background graphics, text and sprite graphics. Eiji instead used the sprites as tiles for the background, making programming and circuit design a tad simpler.<br />
<br />
The US president Marty was also an accomplished musician, magician and movie actor. Kept that to himself, though. Amazing talents.<br />
<br />
John Barone ended up marrying Susan Jarocki, who's dad Stan Jarocki ran this company called Bally-Midway. Games ran in that family, I guess.<br />
<br />
The tech department was an absolute blast. Between big band music, Rush Limbaugh, death metal and some absolutely wierd music, it was noisy and fun. For the entire US branch, though as Chad mentions, us being a broken arm, we did the best we could and had a lot of fun doing it.<br />
<br />
One competition which was a full tradition was a daily tech depamrtment competition of Thrash rally set up in 4 cabinets. I had my own cabinet modified with a steering wheel (showed at a trade show but no interest) which helped out immensely. The competition was quite insane and we all had a real good time.<br />
<br />
Romstar had been tied in with SNK back and forth, from being originally SNK USA to employees trading back and forth. At least 5 employees of Romstar (including yours truly) ended up at SNK at various times.<br />
<br />
Late night shipping runs included major pizza party action. We all worked like bulldogs and got the product out the door. When shipping time came round, RUSH was the order of the day.<br />
<br />
The Samurai Shodown trade advertisement with several people worshipping a cabinet with the "we're not worthy" included Game Lord, his sidekick George, some of the warehouse crew and the two sons of our graphics artist.<br />
<br />
The funniest program bomb I ever ran across personally was from a curious invention I was doing, to make a Neo Geo into a redemption game, giving out tickets. It had some good interest at the show and it earned like mad at the local test arcade. Then one morning, a bit of forgotten programming showed itself when the ticket photocell got dirty and gave out over 7,000 tickets. Whoops! (the program rewrite didnt finish as that is when the closure announcement came in). <br />
<br />
I had worked at Romstar previously, we had connectes with SNK. Back when the SNK home division was first started, Mr. Yasuki had sent me over to help solve some video output issues with the TV interface which was causing FCC failure problems. The solve was slightly detuning the crystal and the extra grounding wires to the crystal and area.<br />
<br />
Romstar had moved up North as Capcom was part owner and had it decided, and it was so. I was born and grew up in the LA area and did not want to move. It was a sad time, there were many tears. I wrote a sad poem about it all in rememberance. I will post it.<br />
<br />
Mr. Yasuki pulled strings and got me into SNK which was in a bigger building doing arcade. At Romstar, we had licensed the 1 slot system for sale as a conversion kit. I still remember the first 10,000 boards came in, a HUGE stack of boxes, maybe 40 feet deep, 10 feet tall, 10-20 feet wide. Took up a LOT of the warehouse.<br />
<br />
Romstar was quite mellow and an adventure. Had it stayed, I would have had my first inhouse 100% programmed game within a year, I was helping develop the Terra 2 arcade system there. It was 286 based with CPLD graphic chip systems to allow the graphicvs path to be revised. I do have the board layout somewhere, I will have to post it someday. The main board was designed by Doug Hughes, who designed the hardware system used by Taito for the game Qix (an entirely American game with no Japanes programming or design whatsoever).<br />
<br />
SNK seemed tougher at first but I got the rhythmn. We all had a lot of fun and creativity ran well. For breaks, we all competed in darts and Thrash Rally 2 times a day. I had designed a steering wheel control panel and pedal and it kept me int he race since I usually suck at games, and I Was able to keep up. The Thrash contests were on 4 cabinets, and we were SAVAGE players. Plenty of smack talk aqnd competition.<br />
<br />
I did the arcade repairs, answered phones and tech department things. I also did design work and odd things.<br />
<br />
SNK went up north due to the Neo Print, I got a job as a distributor. Ended up hating that job since it became a Dilbert cartoon come to life. Ironically, the home division guy at SNK is working there at that same distributor right now.<br />
<br />
My present job is engineering, doing circuit board design of phone and security system entry ways. VERY fun job.<br />
<br />
Anyhoo, that is why I still remember my neo tech stuph. But yup, it was a job that stood out. Lots of fun. The only reason I give it a 2-3% less than Romstar and present job, it seemed a tiny bit stiff at first, but once I got the hang and rhythmn, it all worked out. Personal wise, we were great, did Christmas walks together, partied together. Was very much a family.</div>HeavyMachineGunhttps://www.neo-geo.com/wiki/index.php?title=Neo_Geo_MVS_Arcade_System&diff=4307Neo Geo MVS Arcade System2012-02-13T17:47:31Z<p>HeavyMachineGun: /* See Also */</p>

<br />
The '''[[MVS]]''' (Multi Video System), as the [[Neo-Geo]] was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-[[slot]], 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />

== Collecting ==<br />
<br />
=== Loose Cartridges ===<br />
<br />
[[Image:KOF96KIT.jpg|300px|thumb|A complete King of Fighters '96 MVS kit.]]<br />
<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
[[Image:Bootleg_neo_geo_cup_98_prg.jpg|300px|thumb|An example of a bootleg MVS game]]<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies.<br />

<br />
== Modification ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />
<br />
<center>[[File:Analogue Walnut Set.jpg]]</center><br />
<br />
Other noteworthy CMVS modders include: <br />

* SuperGoose79<br />
* kpj (operates Neotropolis)<br />

== Collecting ==<br />
<br />
=== Loose Cartridges ===<br />
<br />

<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
[[Image:Bootleg_neo_geo_cup_98_prg.jpg|300px|thumb|An example of a bootleg MVS game]]<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies.<br />

<br />
== Modification ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

<hr />
<div>The '''[[Neo-Geo]]''' (ネオジオ) (officially printed as NEO•GEO) is a cartridge-based arcade and home video game system released on July 1, 1991 by Japanese game company SNK. Being in the Fourth generation of Gaming, it was the first console in the former Neo Geo family, which only lived through the 1990s. The hardware featured comparatively colourful 2D graphics. It's arcade counterpart is the [[Neo Geo MVS Arcade System]].<br />
<br />
The Neo Geo system was marketed as a very costly home console, commonly referred to today as the AES (Advanced Entertainment System). The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 16-bit system with an 8-bit Zilog Z80 as coprocessor. The coprocessor was used as a CPU, and for sound processing. The Super Nintendo and Sega Genesis also had similar co-processors, with neither Sega nor Nintendo claiming they were 24-bit.<br />
<br />
== History ==<br />
<br />
[[Image:Home_cart_system.jpg|300px|thumb|right]]<br />
<br />
Initially, the (AES) home system was only available for rent to commercial establishments, such as hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a $650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January, 1990 in Osaka, Japan. Compared to the other 16-bit consoles of the time, Neo Geo's graphics and sound were vastly superior. The MVS was one of the most powerful arcade units at the time. Furthermore, since the AES was identical to its arcade counterpart, the MVS, arcade titles released for the home market were perfect translations. Although its high price tag kept it out of the mainstream gaming market, a strong game lineup likely contributed to the cult status of the Neo Geo, enabling it to outlast the more popular Sega Mega Drive/Genesis.<br />
<br />
In the United States, the console was planned to debut at $599 USD and included two joystick controllers and a game, either Baseball Stars Professional or NAM-1975. However, the price was raised and its American launch debuted at $649.99. This package was known as the "Gold System." Later, the "Gold System" was bundled with Magician Lord and Fatal Fury. The system was also released in a "Silver System" package for $399.99, which included one joystick controller and did not include a game. Other games were priced at about $200 (and up). With these "premium" prices, though, most gamers weren't able to afford the system, so the console was only accessible to a niche market.<br />
<br />
The home system featured two CPUs: the 16-bit Motorola 68000 main processor running at 12 MHz and the 8-bit Zilog Z80 coprocessor running at 4 MHz. A custom video chipset allowed the system to display 4,096 colors and 380 individual sprites onscreen simultaneously, while the onboard Yamaha YM2610 sound chip gave the system 15 channels of sound with seven channels reserved specifically for digital sound effects. When realtime 3D graphics stormed the arcade industry, the Neo Geo's hardware was unable to follow along. The longevity of Neo Geo games kept it alive in arcades, particularly in Japan, where the newest installment of its flagship franchise, The King of Fighters, caused a stir with every new release.<br />
<br />
The last official game by SNK for the Neo Geo system, Samurai Shodown V Special, was released in 2004. SNK decided to abandon the video game hardware business due to the rampant piracy of game-cartridges, which SNK believed was partially responsible for its bankruptcy in 2001. SNK ceased to manufacture home consoles by the end of 1997, but continued to release games for both arcade and home for another 8 years.<br />
<br />
Measured from the introduction of the arcade hardware in 1990 to the release of the last official home cartridge in 2004, the Neo Geo enjoyed a market lifespan of fourteen years, making it the second longest-lived arcade or home console system ever produced (after Atari 2600). On August 31, 2007, SNK stopped offering maintenance and repairs to Neo Geo home consoles, handhelds, and games. However, they will continue to repair their MVS arcade hardware.<br />
<br />
<center>[[Image:Neo-Geo-AES-Console-Set-small.png|600px]]</center><br />
<br />
== Technical Aspects ==<br />
<br />
Each joystick controller was 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × 2.5 in.) and contained the same four-button layout as the arcade MVS cabinet.<br />
<br />
The arcade machines had a memory card system by which a player could save a game to return to at a later time and could also be used to continue play on the SNK home console of the same name.<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial [[Homebrew]] games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />
=== Graphics ===<br />
<br />
Unlike most other video game consoles of its time, the Neo Geo did not use tilemap background layers. Instead, it relied exclusively on drawing sprites to create the background. Sprites are vertical strips which are 16 pixels wide, and can be 16 to 512 pixels tall. By laying multiple sprites side by side, the system can simulate a background layer. The system can draw up to 384 sprites on the screen at a time, and up to 96 per scanline.<br />

<br />
=== Home Cartridges ===<br />
<br />
There is a thriving collector's scene for the Neo Geo home systems, especially the original AES home console. This is mainly because of the limited runs received by cartridges, the massive arcade library available, and the system's reputation as a 2D powerhouse. It is still common even to this day for both Neo Geo consoles and cartridges to fetch extremely high prices on eBay and other auction websites, particularly English versions of cartridges as these were produced in lower quantities. A handful of the rarest Neo Geo games can sell for well over $1,000 on eBay. This gives the system an almost cult following, as owners see the system as more of an "investment" rather than an ordinary videogame console. This leads to high resale value on most Neo Geo systems and games and makes the console a "must-have" for a number of video game collectors. The most expensive cartridge for the Neo Geo home system is the European-localized version of Kizuna Encounter: There are only five known copies of the game, with the most recently sold copy selling for about $12,000 USD.<br />
<br />
=== Conversions === <br />
<br />
[[Conversion]]s are NGH/AES cartridges that have had their original Mask ROMs removed and replaced with those of an MVS cartridge, typically from an MVS game which had no home cart release, or sometimes one that had a very rare home cart release. In a few cases, conversions are made with EPROMs instead of Mask ROMs. Discussion is often a very touchy subject and thus information is not widely known on their creation. <br />
<br />
Generally, the value of a conversion is determined by the cost of parts (MVS cartridge, donor AES cart and label/insert) and not much more. Mask ROM conversions are usually worth only a fraction of an authentic NGH/AES copy. Ones made from EPROMs are worth considerably less. Conversions made from MVS exclusives are sometimes worth a bit more. <br />
<br />
In recent years, NGH/AES conversions have become increasingly advanced and near-identical to their authentic counterparts. So much that in some cases, the only way to distinguish between a conversion and an authentic copy is to have both on hand to meticulously compare. As a result the NGH/AES collector's market has become increasingly dangerous. Potential buyers are always highly encouraged to research a particular copy's history and integrity before they buy.<br />
<br />
On a related footnote, while often labeled as a stereotype, France has been accused and blamed for spearheading the advancement of conversions over the years. Some allegations against respected French collectors tend to be unfounded, while other cases have been proven with evidence. <br />
<br />
=== Freaked Cartridges=== <br />
<br />
A directly related subset of the home cartridges market, freaked cartridges are NGH/AES games that have been damaged in any number of ways by illegal distribution outfit Neo Geo Freak. The type of damage ranges from light cases of the occasional NGF sticker and re-printed case insert, to extreme examples of void stickers being plastered on the insert, cartridge and manual pages. The reasoning behind such damage isn't well known. <br />
<br />
In today's market, freaked cartridges are not very common and hardly change hands, likely from the drop in perceived value. Freaked carts with only a reprinted insert aren't worth much less than a legit copy, while horrifically freaked cartridges are always valued much less than pristine equivalents. <br />
<br />
== Modification ==<br />
<br />
[[Image:Modded_neo_geo2.jpg|300px|thumb|right|A Neo Geo console modded with Composite, S-Video, Component and Stereo Sound]]<br />
<br />
A popular facet of the Neo Geo that has grown over the years is the practice of modding NGH hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the Neo Geo. Commonly installed mods include: <br />
<br />
* S-Video (using the original Sony CXA1145 video encoder)<br />
* Component (using a new video encoder)<br />
* Universe BIOS (replacing the original stock BIOS<br />
* Debug BIOS (made obsolete by the Universe BIOS)<br />
* RGB Bypass (used to increase RGB video output fidelity)<br />
* Power LED (typically installed inside the reset button)<br />
* Replacement controller buttons/joystick (typically performed on Old Style sticks, sometimes HORI sticks)<br />
<br />
Most fan modding is done by individuals for their own personal use, though some people do it as a service. Popular service providers include:<br />
<br />
* Xian Xi (frequents Neo-Geo.com and runs Jamma Nation X)<br />
* JMKurtz <br />
* kpj (operates Neotropolis)<br />

<br />
And here's some things that couldn't easily be condensed into the list, or were too lacking in complete information: <br />
<br />
* In the NeoGeoCD version of SamShoII you can play as Kuroko (the referee-guy) by standing on some character, pressing up, down, up, down, left, right, left, right, blablabla or something. His weapon are the flags he always uses and he has a big fireball as in Art of Fighting style.<br />
<br />
* AOF 3 (i believe) has time release secrets/events. Something happens, I believe on Ryo's, Roberts, etc. birthdays. I'd find the thread, but the search is broken right now. <br />
<br />
* The only reason I was able to beat Sengoku 1 on AES was because of a ridiculous exploit trick I accidentally found: jumping constantly. If you get a up a power up ball, the new sword won't form in your hands till you stop jumping! So you get the most time out of every power up in the game because you chose when to activate the next one. <br />
<br />
* A BackGround Charecter in Metal Slug III is based on Ben Herman. <br />
<br />
* In Metal Slug X, if you use a debug BIOS, you can access "secret" incomplete-looking levels that appear to be level areas used in Metal Slug 3! You can wander around these levels and use vehicles such as a submarine and gyrocopter just like in MS3. If you were wondering why the meg count increased by over 100 between Metal Slug 2 and X, then this is your answer. There are also other debugging features that you can toggle on and off while exploring the areas. <br />
<br />
* in the King Of Fighters for the US Neo-Geo CD/home cart, Mai's boobies do not bouncy-bouncy. However, this "feature" was accessible with a code which was at the high score screen, press A and D on controller 1 simultaneously as you press B and C on controller 2, this code also made the blood appear.<br />
<br />
* In Neo Turf Masters, if you select the long hitter Mandel, there are several short cuts to albatrosses and even hole in ones. One such adventure is the Island shot on the Austrailian course. By hitting a full hard shot at the (lowest point) highest trajectory, the ball will bounce off the island and roll across the green nearest the pin. Your next shot will be for Albatross.. Oh yeah, practice makes perfect. If done just right the graphics get really strange. This is kinda like an Easter Egg Neo style. <br />
<br />
* In Pulstar, anyone ever notice how the default high scores are the chassis codes of Japanese cars?<br />
-R32 (Nissan Skyline R32)<br />
-Z32 (Nissan 300ZX Z32)<br />
-FD3 (Mazda RX7 FD3S)<br />
-JZA (Supra MkIII/IV JZA70/JZA80)<br />
-NSX (Honda/Acura NSX) <br />
<br />
<br />
* Did you know in Magical Drop 3 there are 6 secret characters that can be selected if you know the tarot card number of any of the characters? Just hit "C" 3 times while over the character whose number you know, when the timer reaches their number.<br />
<br />
20 - Judgment<br />
19 - Sun<br />
17 - Star<br />
15 - Devil<br />
13 - Death<br />
11 - Justice<br />
8 - Strength<br />
7 - Chariot<br />
6 - Lovers<br />
5 - Hierophant<br />
4 - Emperor<br />
3 - Empress<br />
2 - High Priestess<br />
1 - Magician<br />
0 - Fool<br />
<br />
Also Father Strength can be selected by selecting Strength by holding "C" and pressing "A & B" at the same time.<br />
<br />
<br />
* older NGH units have wrong values for the video circuitry in disregard of the values recommended by sony at the video encoder datasheet, this results in a darker picture, snk fixed the mistake at the later units and so they have a much brighter picture.<br />
<br />
The myth that the earlier units have better picture was caused by the latest and more common NGH revision the 3-6 which consists of half of the NGH systems ever made, it has a design problem at the video circuit that causes vertical lines when displaying RGB. It's easily fixed making it perform on par with board revision 3-5 which is the best stock unit as for RGB quality.<br />
<br />
The original and inconclusive research done by nfg, he had no access to most of the systems revisions, made wrong assumptions and didn't knew how to fix the RGB video problem at the 3-6 unit which caused striping.<br />
http://nfggames.com/games/neorgb2/<br />
<br />
MKL research on the matter, with access to all board revisions a conclusive explanation is offered, since the picture links are broken I'll post another link to the fix below.<br />

=== Bits on Pre-Neo Geo ===<br />
<br />
The Alpha68k (name from MAME) is more than likely an early version of the Neo Geo hardware. This can be verified by looking at the games in MAME. Alpha68k games are 256x224 using 2048 colors. The Neo Geo is 320x224 using 4096 colors.<br />
<br />
The flip bit for the sprites is bit 0 and 1 for Neo Geo, and bits 15 and 16 for the Alpha68k system. (Taken right from the MAME source).<br />
<br />
I've always wondered why they didn't have a tilemap like 99.99% of the other hardware of the time.<br />
I'm not sure about making programming easier (more flexible maybe), but the circuit design make sense. <br />
<br />
the Alpha68k, was used by Alpha Denshi as early at 1987, and SNK in 1988. SNK also started using the SNK68k system is 1988. The systems components and memory map are very close in design. Then there's the Beast Busters hardware, which isn't close to either, but does have the scaled sprites. Interesting is that the hardware components of the Neo Geo (12 Mhz 68000 4 Mhz Z80 YM2610 sound chip) more closely match the Beast Busters hardware than any other. There is almost no connection between this board and any of the others, though.<br />
<br />
SNK never designed the Neo Geo hardware system. Eiji Fukatsu himself designed it as an improved version of his 68K system. It features the essential sprite tiling system compressed into 3 chips, a scalar table in ROM function and a redone sound system as well as cartridge interface. <br />
<br />
=== Bits on the Corporate Neo Geo ===<br />
<br />
By Nightmare Tony: <br />
<br />
Kernow, Forever did remmeber right. If you have a schematic to any Neo geo system, it will have Alpha Denshi on it, along with their head wildman, Eiji Fukatsu. The system he actually did as a full board previously, first starting with a game called Battlefield (renamed to Time Soldiers). Romstar had the board redone also as Sky Soldiers and Gold Medalist. Sky Adventure also used the same system.<br />
<br />
As a general rule, graphic systems of the time used a background graphics, text and sprite graphics. Eiji instead used the sprites as tiles for the background, making programming and circuit design a tad simpler.<br />
<br />
The US president Marty was also an accomplished musician, magician and movie actor. Kept that to himself, though. Amazing talents.<br />
<br />
John Barone ended up marrying Susan Jarocki, who's dad Stan Jarocki ran this company called Bally-Midway. Games ran in that family, I guess.<br />
<br />
The tech department was an absolute blast. Between big band music, Rush Limbaugh, death metal and some absolutely wierd music, it was noisy and fun. For the entire US branch, though as Chad mentions, us being a broken arm, we did the best we could and had a lot of fun doing it.<br />
<br />
One competition which was a full tradition was a daily tech depamrtment competition of Thrash rally set up in 4 cabinets. I had my own cabinet modified with a steering wheel (showed at a trade show but no interest) which helped out immensely. The competition was quite insane and we all had a real good time.<br />
<br />
Romstar had been tied in with SNK back and forth, from being originally SNK USA to employees trading back and forth. At least 5 employees of Romstar (including yours truly) ended up at SNK at various times.<br />
<br />
Late night shipping runs included major pizza party action. We all worked like bulldogs and got the product out the door. When shipping time came round, RUSH was the order of the day.<br />
<br />
The Samurai Shodown trade advertisement with several people worshipping a cabinet with the "we're not worthy" included Game Lord, his sidekick George, some of the warehouse crew and the two sons of our graphics artist.<br />
<br />
The funniest program bomb I ever ran across personally was from a curious invention I was doing, to make a Neo Geo into a redemption game, giving out tickets. It had some good interest at the show and it earned like mad at the local test arcade. Then one morning, a bit of forgotten programming showed itself when the ticket photocell got dirty and gave out over 7,000 tickets. Whoops! (the program rewrite didnt finish as that is when the closure announcement came in). <br />
<br />
I had worked at Romstar previously, we had connectes with SNK. Back when the SNK home division was first started, Mr. Yasuki had sent me over to help solve some video output issues with the TV interface which was causing FCC failure problems. The solve was slightly detuning the crystal and the extra grounding wires to the crystal and area.<br />
<br />
Romstar had moved up North as Capcom was part owner and had it decided, and it was so. I was born and grew up in the LA area and did not want to move. It was a sad time, there were many tears. I wrote a sad poem about it all in rememberance. I will post it.<br />
<br />
Mr. Yasuki pulled strings and got me into SNK which was in a bigger building doing arcade. At Romstar, we had licensed the 1 slot system for sale as a conversion kit. I still remember the first 10,000 boards came in, a HUGE stack of boxes, maybe 40 feet deep, 10 feet tall, 10-20 feet wide. Took up a LOT of the warehouse.<br />
<br />
Romstar was quite mellow and an adventure. Had it stayed, I would have had my first inhouse 100% programmed game within a year, I was helping develop the Terra 2 arcade system there. It was 286 based with CPLD graphic chip systems to allow the graphicvs path to be revised. I do have the board layout somewhere, I will have to post it someday. The main board was designed by Doug Hughes, who designed the hardware system used by Taito for the game Qix (an entirely American game with no Japanes programming or design whatsoever).<br />
<br />
SNK seemed tougher at first but I got the rhythmn. We all had a lot of fun and creativity ran well. For breaks, we all competed in darts and Thrash Rally 2 times a day. I had designed a steering wheel control panel and pedal and it kept me int he race since I usually suck at games, and I Was able to keep up. The Thrash contests were on 4 cabinets, and we were SAVAGE players. Plenty of smack talk aqnd competition.<br />
<br />
I did the arcade repairs, answered phones and tech department things. I also did design work and odd things.<br />
<br />
SNK went up north due to the Neo Print, I got a job as a distributor. Ended up hating that job since it became a Dilbert cartoon come to life. Ironically, the home division guy at SNK is working there at that same distributor right now.<br />
<br />
My present job is engineering, doing circuit board design of phone and security system entry ways. VERY fun job.<br />
<br />
Anyhoo, that is why I still remember my neo tech stuph. But yup, it was a job that stood out. Lots of fun. The only reason I give it a 2-3% less than Romstar and present job, it seemed a tiny bit stiff at first, but once I got the hang and rhythmn, it all worked out. Personal wise, we were great, did Christmas walks together, partied together. Was very much a family.</div>HeavyMachineGunhttps://www.neo-geo.com/wiki/index.php?title=Neo_Geo_MVS_Arcade_System&diff=4303Neo Geo MVS Arcade System2012-02-12T20:02:16Z<p>HeavyMachineGun: /* Consolization */</p>

<br />
The '''[[MVS]]''' (Multi Video System), as the [[Neo-Geo]] was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-[[slot]], 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />

== Collecting ==<br />
<br />
=== Loose Cartridges ===<br />
<br />
[[Image:KOF96KIT.jpg|300px|thumb|A complete King of Fighters '96 MVS kit.]]<br />
<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
[[Image:Bootleg_neo_geo_cup_98_prg.jpg|300px|thumb|An example of a bootleg MVS game]]<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies.<br />

<br />
== Modification ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />
<br />
<center>[[File:Analogue Walnut Set.jpg]]</center><br />
<br />
Other noteworthy CMVS modders include: <br />
<br />
* Xian Xi (frequents Neo-Geo.com and operates Jamma Nation X)<br />
* SuperGoose79<br />
* kpj (operates Neotropolis)<br />

<hr />
<div>The '''[[Neo-Geo]]''' (ネオジオ) (officially printed as NEO•GEO) is a cartridge-based arcade and home video game system released on July 1, 1991 by Japanese game company SNK. Being in the Fourth generation of Gaming, it was the first console in the former Neo Geo family, which only lived through the 1990s. The hardware featured comparatively colourful 2D graphics. It's arcade counterpart is the [[Neo Geo MVS Arcade System]].<br />
<br />
The Neo Geo system was marketed as a very costly home console, commonly referred to today as the AES (Advanced Entertainment System). The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 16-bit system with an 8-bit Zilog Z80 as coprocessor. The coprocessor was used as a CPU, and for sound processing. The Super Nintendo and Sega Genesis also had similar co-processors, with neither Sega nor Nintendo claiming they were 24-bit.<br />
<br />
== History ==<br />
<br />
[[Image:Home_cart_system.jpg|300px|thumb|right]]<br />
<br />
Initially, the (AES) home system was only available for rent to commercial establishments, such as hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a $650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January, 1990 in Osaka, Japan. Compared to the other 16-bit consoles of the time, Neo Geo's graphics and sound were vastly superior. The MVS was one of the most powerful arcade units at the time. Furthermore, since the AES was identical to its arcade counterpart, the MVS, arcade titles released for the home market were perfect translations. Although its high price tag kept it out of the mainstream gaming market, a strong game lineup likely contributed to the cult status of the Neo Geo, enabling it to outlast the more popular Sega Mega Drive/Genesis.<br />
<br />
In the United States, the console was planned to debut at $599 USD and included two joystick controllers and a game, either Baseball Stars Professional or NAM-1975. However, the price was raised and its American launch debuted at $649.99. This package was known as the "Gold System." Later, the "Gold System" was bundled with Magician Lord and Fatal Fury. The system was also released in a "Silver System" package for $399.99, which included one joystick controller and did not include a game. Other games were priced at about $200 (and up). With these "premium" prices, though, most gamers weren't able to afford the system, so the console was only accessible to a niche market.<br />
<br />
The home system featured two CPUs: the 16-bit Motorola 68000 main processor running at 12 MHz and the 8-bit Zilog Z80 coprocessor running at 4 MHz. A custom video chipset allowed the system to display 4,096 colors and 380 individual sprites onscreen simultaneously, while the onboard Yamaha YM2610 sound chip gave the system 15 channels of sound with seven channels reserved specifically for digital sound effects. When realtime 3D graphics stormed the arcade industry, the Neo Geo's hardware was unable to follow along. The longevity of Neo Geo games kept it alive in arcades, particularly in Japan, where the newest installment of its flagship franchise, The King of Fighters, caused a stir with every new release.<br />
<br />
The last official game by SNK for the Neo Geo system, Samurai Shodown V Special, was released in 2004. SNK decided to abandon the video game hardware business due to the rampant piracy of game-cartridges, which SNK believed was partially responsible for its bankruptcy in 2001. SNK ceased to manufacture home consoles by the end of 1997, but continued to release games for both arcade and home for another 8 years.<br />
<br />
Measured from the introduction of the arcade hardware in 1990 to the release of the last official home cartridge in 2004, the Neo Geo enjoyed a market lifespan of fourteen years, making it the second longest-lived arcade or home console system ever produced (after Atari 2600). On August 31, 2007, SNK stopped offering maintenance and repairs to Neo Geo home consoles, handhelds, and games. However, they will continue to repair their MVS arcade hardware.<br />
<br />
<center>[[Image:Neo-Geo-AES-Console-Set-small.png|600px]]</center><br />
<br />
== Technical Aspects ==<br />
<br />
Each joystick controller was 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × 2.5 in.) and contained the same four-button layout as the arcade MVS cabinet.<br />
<br />
The arcade machines had a memory card system by which a player could save a game to return to at a later time and could also be used to continue play on the SNK home console of the same name.<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial [[Homebrew]] games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />
=== Graphics ===<br />
<br />
Unlike most other video game consoles of its time, the Neo Geo did not use tilemap background layers. Instead, it relied exclusively on drawing sprites to create the background. Sprites are vertical strips which are 16 pixels wide, and can be 16 to 512 pixels tall. By laying multiple sprites side by side, the system can simulate a background layer. The system can draw up to 384 sprites on the screen at a time, and up to 96 per scanline.<br />

<br />
=== Home Cartridges ===<br />
<br />
There is a thriving collector's scene for the Neo Geo home systems, especially the original AES home console. This is mainly because of the limited runs received by cartridges, the massive arcade library available, and the system's reputation as a 2D powerhouse. It is still common even to this day for both Neo Geo consoles and cartridges to fetch extremely high prices on eBay and other auction websites, particularly English versions of cartridges as these were produced in lower quantities. A handful of the rarest Neo Geo games can sell for well over $1,000 on eBay. This gives the system an almost cult following, as owners see the system as more of an "investment" rather than an ordinary videogame console. This leads to high resale value on most Neo Geo systems and games and makes the console a "must-have" for a number of video game collectors. The most expensive cartridge for the Neo Geo home system is the European-localized version of Kizuna Encounter: There are only five known copies of the game, with the most recently sold copy selling for about $12,000 USD.<br />
<br />
=== Conversions === <br />
<br />
[[Conversion]]s are NGH/AES cartridges that have had their original Mask ROMs removed and replaced with those of an MVS cartridge, typically from an MVS game which had no home cart release, or sometimes one that had a very rare home cart release. In a few cases, conversions are made with EPROMs instead of Mask ROMs. Discussion is often a very touchy subject and thus information is not widely known on their creation. <br />
<br />
Generally, the value of a conversion is determined by the cost of parts (MVS cartridge, donor AES cart and label/insert) and not much more. Mask ROM conversions are usually worth only a fraction of an authentic NGH/AES copy. Ones made from EPROMs are worth considerably less. Conversions made from MVS exclusives are sometimes worth a bit more. <br />
<br />
In recent years, NGH/AES conversions have become increasingly advanced and near-identical to their authentic counterparts. So much that in some cases, the only way to distinguish between a conversion and an authentic copy is to have both on hand to meticulously compare. As a result the NGH/AES collector's market has become increasingly dangerous. Potential buyers are always highly encouraged to research a particular copy's history and integrity before they buy.<br />
<br />
On a related footnote, while often labeled as a stereotype, France has been accused and blamed for spearheading the advancement of conversions over the years. Some allegations against respected French collectors tend to be unfounded, while other cases have been proven with evidence. <br />
<br />
=== Freaked Cartridges=== <br />
<br />
A directly related subset of the home cartridges market, freaked cartridges are NGH/AES games that have been damaged in any number of ways by illegal distribution outfit Neo Geo Freak. The type of damage ranges from light cases of the occasional NGF sticker and re-printed case insert, to extreme examples of void stickers being plastered on the insert, cartridge and manual pages. The reasoning behind such damage isn't well known. <br />
<br />
In today's market, freaked cartridges are not very common and hardly change hands, likely from the drop in perceived value. Freaked carts with only a reprinted insert aren't worth much less than a legit copy, while horrifically freaked cartridges are always valued much less than pristine equivalents. <br />

== Modification ==<br />
<br />
[[Image:Modded_neo_geo2.jpg|300px|thumb|right|A Neo Geo console modded with Composite, S-Video, Component and Stereo Sound]]<br />
<br />
A popular facet of the Neo Geo that has grown over the years is the practice of modding NGH hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the Neo Geo. Commonly installed mods include: <br />
<br />
* S-Video (using the original Sony CXA1145 video encoder)<br />
* Component (using a new video encoder)<br />
* Universe BIOS (replacing the original stock BIOS<br />
* Debug BIOS (made obsolete by the Universe BIOS)<br />
* RGB Bypass (used to increase RGB video output fidelity)<br />
* Power LED (typically installed inside the reset button)<br />
* Replacement controller buttons/joystick (typically performed on Old Style sticks, sometimes HORI sticks)<br />
<br />
Most fan modding is done by individuals for their own personal use, though some people do it as a service. Popular service providers include:<br />
<br />
* Xian Xi (frequents Neo-Geo.com and runs Jamma Nation X)<br />
* JMKurtz <br />
* kpj (operates Neotropolis)<br />

<br />
The '''[[MVS]]''' (Multi Video System), as the [[Neo-Geo]] was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-[[slot]], 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />

In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />

== Collecting ==<br />
<br />
=== Loose Cartridges ===<br />
<br />
[[Image:KOF96KIT.jpg|300px|thumb|A complete King of Fighters '96 MVS kit.]]<br />
<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
[[Image:Bootleg_neo_geo_cup_98_prg.jpg|300px|thumb|An example of a bootleg MVS game]]<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies.<br />

== Modification ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />

<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />

== Collecting ==<br />
<br />
=== Loose Cartridges ===<br />
<br />
[[Image:KOF96KIT.jpg|300px|thumb|A complete King of Fighters '96 MVS kit.]]<br />
<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
[[Image:Bootleg_neo_geo_cup_98_prg.jpg|300px|thumb|An example of a bootleg MVS game]]<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies.<br />
<br />
== Modification ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

<hr />
<div>The '''[[Neo-Geo]]''' (ネオジオ) (officially printed as NEO•GEO) is a cartridge-based arcade and home video game system released on July 1, 1991 by Japanese game company SNK. Being in the Fourth generation of Gaming, it was the first console in the former Neo Geo family, which only lived through the 1990s. The hardware featured comparatively colourful 2D graphics. It's arcade counterpart is the [[Neo Geo MVS Arcade System]].<br />
<br />
The Neo Geo system was marketed as a very costly home console, commonly referred to today as the AES (Advanced Entertainment System). The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 16-bit system with an 8-bit Zilog Z80 as coprocessor. The coprocessor was used as a CPU, and for sound processing. The Super Nintendo and Sega Genesis also had similar co-processors, with neither Sega nor Nintendo claiming they were 24-bit.<br />
<br />
== History ==<br />
<br />
[[Image:Home_cart_system.jpg|300px|thumb|right]]<br />
<br />
Initially, the (AES) home system was only available for rent to commercial establishments, such as hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a $650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January, 1990 in Osaka, Japan. Compared to the other 16-bit consoles of the time, Neo Geo's graphics and sound were vastly superior. The MVS was one of the most powerful arcade units at the time. Furthermore, since the AES was identical to its arcade counterpart, the MVS, arcade titles released for the home market were perfect translations. Although its high price tag kept it out of the mainstream gaming market, a strong game lineup likely contributed to the cult status of the Neo Geo, enabling it to outlast the more popular Sega Mega Drive/Genesis.<br />
<br />
In the United States, the console was planned to debut at $599 USD and included two joystick controllers and a game, either Baseball Stars Professional or NAM-1975. However, the price was raised and its American launch debuted at $649.99. This package was known as the "Gold System." Later, the "Gold System" was bundled with Magician Lord and Fatal Fury. The system was also released in a "Silver System" package for $399.99, which included one joystick controller and did not include a game. Other games were priced at about $200 (and up). With these "premium" prices, though, most gamers weren't able to afford the system, so the console was only accessible to a niche market.<br />
<br />
The home system featured two CPUs: the 16-bit Motorola 68000 main processor running at 12 MHz and the 8-bit Zilog Z80 coprocessor running at 4 MHz. A custom video chipset allowed the system to display 4,096 colors and 380 individual sprites onscreen simultaneously, while the onboard Yamaha YM2610 sound chip gave the system 15 channels of sound with seven channels reserved specifically for digital sound effects. When realtime 3D graphics stormed the arcade industry, the Neo Geo's hardware was unable to follow along. The longevity of Neo Geo games kept it alive in arcades, particularly in Japan, where the newest installment of its flagship franchise, The King of Fighters, caused a stir with every new release.<br />
<br />
The last official game by SNK for the Neo Geo system, Samurai Shodown V Special, was released in 2004. SNK decided to abandon the video game hardware business due to the rampant piracy of game-cartridges, which SNK believed was partially responsible for its bankruptcy in 2001. SNK ceased to manufacture home consoles by the end of 1997, but continued to release games for both arcade and home for another 8 years.<br />
<br />
Measured from the introduction of the arcade hardware in 1990 to the release of the last official home cartridge in 2004, the Neo Geo enjoyed a market lifespan of fourteen years, making it the second longest-lived arcade or home console system ever produced (after Atari 2600). On August 31, 2007, SNK stopped offering maintenance and repairs to Neo Geo home consoles, handhelds, and games. However, they will continue to repair their MVS arcade hardware.<br />
<br />
<center>[[Image:Neo-Geo-AES-Console-Set-small.png|600px]]</center><br />
<br />
== Technical Aspects ==<br />
<br />
Each joystick controller was 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × 2.5 in.) and contained the same four-button layout as the arcade MVS cabinet.<br />
<br />
The arcade machines had a memory card system by which a player could save a game to return to at a later time and could also be used to continue play on the SNK home console of the same name.<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial [[Homebrew]] games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />
=== Graphics ===<br />
<br />
Unlike most other video game consoles of its time, the Neo Geo did not use tilemap background layers. Instead, it relied exclusively on drawing sprites to create the background. Sprites are vertical strips which are 16 pixels wide, and can be 16 to 512 pixels tall. By laying multiple sprites side by side, the system can simulate a background layer. The system can draw up to 384 sprites on the screen at a time, and up to 96 per scanline.<br />

<br />
=== Home Cartridges ===<br />
<br />
There is a thriving collector's scene for the Neo Geo home systems, especially the original AES home console. This is mainly because of the limited runs received by cartridges, the massive arcade library available, and the system's reputation as a 2D powerhouse. It is still common even to this day for both Neo Geo consoles and cartridges to fetch extremely high prices on eBay and other auction websites, particularly English versions of cartridges as these were produced in lower quantities. A handful of the rarest Neo Geo games can sell for well over $1,000 on eBay. This gives the system an almost cult following, as owners see the system as more of an "investment" rather than an ordinary videogame console. This leads to high resale value on most Neo Geo systems and games and makes the console a "must-have" for a number of video game collectors. The most expensive cartridge for the Neo Geo home system is the European-localized version of Kizuna Encounter: There are only five known copies of the game, with the most recently sold copy selling for about $12,000 USD.<br />
<br />
=== Conversions === <br />
<br />
[[Conversion]]s are NGH/AES cartridges that have had their original Mask ROMs removed and replaced with those of an MVS cartridge, typically from an MVS game which had no home cart release, or sometimes one that had a very rare home cart release. In a few cases, conversions are made with EPROMs instead of Mask ROMs. Discussion is often a very touchy subject and thus information is not widely known on their creation. <br />
<br />
Generally, the value of a conversion is determined by the cost of parts (MVS cartridge, donor AES cart and label/insert) and not much more. Mask ROM conversions are usually worth only a fraction of an authentic NGH/AES copy. Ones made from EPROMs are worth considerably less. Conversions made from MVS exclusives are sometimes worth a bit more. <br />
<br />
In recent years, NGH/AES conversions have become increasingly advanced and near-identical to their authentic counterparts. So much that in some cases, the only way to distinguish between a conversion and an authentic copy is to have both on hand to meticulously compare. As a result the NGH/AES collector's market has become increasingly dangerous. Potential buyers are always highly encouraged to research a particular copy's history and integrity before they buy.<br />
<br />
On a related footnote, while often labeled as a stereotype, France has been accused and blamed for spearheading the advancement of conversions over the years. Some allegations against respected French collectors tend to be unfounded, while other cases have been proven with evidence. <br />
<br />
=== Freaked Cartridges=== <br />
<br />
A directly related subset of the home cartridges market, freaked cartridges are NGH/AES games that have been damaged in any number of ways by illegal distribution outfit Neo Geo Freak. The type of damage ranges from light cases of the occasional NGF sticker and re-printed case insert, to extreme examples of void stickers being plastered on the insert, cartridge and manual pages. The reasoning behind such damage isn't well known. <br />
<br />
In today's market, freaked cartridges are not very common and hardly change hands, likely from the drop in perceived value. Freaked carts with only a reprinted insert aren't worth much less than a legit copy, while horrifically freaked cartridges are always valued much less than pristine equivalents. <br />
<br />
== Modification ==<br />
<br />
[[Image:Modded_neo_geo2.jpg|300px|thumb|right|A Neo Geo console modded with Composite, S-Video, Component and Stereo Sound]]<br />
<br />
A popular facet of the Neo Geo that has grown over the years is the practice of modding NGH hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the Neo Geo. Commonly installed mods include: <br />
<br />
* S-Video (using the original Sony CXA1145 video encoder)<br />
* Component (using a new video encoder)<br />
* Universe BIOS (replacing the original stock BIOS<br />
* Debug BIOS (made obsolete by the Universe BIOS)<br />
* RGB Bypass (used to increase RGB video output fidelity)<br />
* Power LED (typically installed inside the reset button)<br />
* Replacement controller buttons/joystick (typically performed on Old Style sticks, sometimes HORI sticks)<br />
<br />
Most fan modding is done by individuals for their own personal use, though some people do it as a service. Popular service providers include:<br />
<br />
* Xian Xi (frequents Neo-Geo.com and runs Jamma Nation X)<br />
* JMKurtz <br />

<br />
The MVS (Multi Video System), as the Neo Geo was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-slot, 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />

In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />

<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
[[Image:Bootleg_neo_geo_cup_98_prg.jpg|300px|thumb|An example of a bootleg MVS game]]<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies.<br />
<br />
== Modification ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

<br />
The MVS (Multi Video System), as the Neo Geo was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-slot, 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />

In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />

<hr />
<div>The '''Neo Geo''' (ネオジオ) (officially printed as NEO•GEO) is a cartridge-based arcade and home video game system released on July 1, 1991 by Japanese game company SNK. Being in the Fourth generation of Gaming, it was the first console in the former Neo Geo family, which only lived through the 1990s. The hardware featured comparatively colourful 2D graphics. It's arcade counterpart is the [[Neo Geo MVS Arcade System]].<br />
<br />
The Neo Geo system was marketed as a very costly home console, commonly referred to today as the AES (Advanced Entertainment System). The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 16-bit system with an 8-bit Zilog Z80 as coprocessor. The coprocessor was used as a CPU, and for sound processing. The Super Nintendo and Sega Genesis also had similar co-processors, with neither Sega nor Nintendo claiming they were 24-bit.<br />
<br />
== History ==<br />
<br />
[[Image:Home_cart_system.jpg|300px|thumb|right]]<br />
<br />
Initially, the (AES) home system was only available for rent to commercial establishments, such as hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a $650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January, 1990 in Osaka, Japan. Compared to the other 16-bit consoles of the time, Neo Geo's graphics and sound were vastly superior. The MVS was one of the most powerful arcade units at the time. Furthermore, since the AES was identical to its arcade counterpart, the MVS, arcade titles released for the home market were perfect translations. Although its high price tag kept it out of the mainstream gaming market, a strong game lineup likely contributed to the cult status of the Neo Geo, enabling it to outlast the more popular Sega Mega Drive/Genesis.<br />
<br />
In the United States, the console was planned to debut at $599 USD and included two joystick controllers and a game, either Baseball Stars Professional or NAM-1975. However, the price was raised and its American launch debuted at $649.99. This package was known as the "Gold System." Later, the "Gold System" was bundled with Magician Lord and Fatal Fury. The system was also released in a "Silver System" package for $399.99, which included one joystick controller and did not include a game. Other games were priced at about $200 (and up). With these "premium" prices, though, most gamers weren't able to afford the system, so the console was only accessible to a niche market.<br />
<br />
The home system featured two CPUs: the 16-bit Motorola 68000 main processor running at 12 MHz and the 8-bit Zilog Z80 coprocessor running at 4 MHz. A custom video chipset allowed the system to display 4,096 colors and 380 individual sprites onscreen simultaneously, while the onboard Yamaha YM2610 sound chip gave the system 15 channels of sound with seven channels reserved specifically for digital sound effects. When realtime 3D graphics stormed the arcade industry, the Neo Geo's hardware was unable to follow along. The longevity of Neo Geo games kept it alive in arcades, particularly in Japan, where the newest installment of its flagship franchise, The King of Fighters, caused a stir with every new release.<br />
<br />
The last official game by SNK for the Neo Geo system, Samurai Shodown V Special, was released in 2004. SNK decided to abandon the video game hardware business due to the rampant piracy of game-cartridges, which SNK believed was partially responsible for its bankruptcy in 2001. SNK ceased to manufacture home consoles by the end of 1997, but continued to release games for both arcade and home for another 8 years.<br />
<br />
Measured from the introduction of the arcade hardware in 1990 to the release of the last official home cartridge in 2004, the Neo Geo enjoyed a market lifespan of fourteen years, making it the second longest-lived arcade or home console system ever produced (after Atari 2600). On August 31, 2007, SNK stopped offering maintenance and repairs to Neo Geo home consoles, handhelds, and games. However, they will continue to repair their MVS arcade hardware.<br />
<br />
<center>[[Image:Neo-Geo-AES-Console-Set-small.png|600px]]</center><br />
<br />
== Technical Aspects ==<br />
<br />
Each joystick controller was 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × 2.5 in.) and contained the same four-button layout as the arcade MVS cabinet.<br />
<br />
The arcade machines had a memory card system by which a player could save a game to return to at a later time and could also be used to continue play on the SNK home console of the same name.<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />

<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />

<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />
=== Graphics ===<br />
<br />
Unlike most other video game consoles of its time, the Neo Geo did not use tilemap background layers. Instead, it relied exclusively on drawing sprites to create the background. Sprites are vertical strips which are 16 pixels wide, and can be 16 to 512 pixels tall. By laying multiple sprites side by side, the system can simulate a background layer. The system can draw up to 384 sprites on the screen at a time, and up to 96 per scanline.<br />

<br />
=== Home Cartridges ===<br />
<br />
There is a thriving collector's scene for the Neo Geo home systems, especially the original AES home console. This is mainly because of the limited runs received by cartridges, the massive arcade library available, and the system's reputation as a 2D powerhouse. It is still common even to this day for both Neo Geo consoles and cartridges to fetch extremely high prices on eBay and other auction websites, particularly English versions of cartridges as these were produced in lower quantities. A handful of the rarest Neo Geo games can sell for well over $1,000 on eBay. This gives the system an almost cult following, as owners see the system as more of an "investment" rather than an ordinary videogame console. This leads to high resale value on most Neo Geo systems and games and makes the console a "must-have" for a number of video game collectors. The most expensive cartridge for the Neo Geo home system is the European-localized version of Kizuna Encounter: There are only five known copies of the game, with the most recently sold copy selling for about $12,000 USD.<br />
<br />
=== Conversions === <br />
<br />
Conversions are NGH/AES cartridges that have had their original Mask ROMs removed and replaced with those of an MVS cartridge, typically from an MVS game which had no home cart release, or sometimes one that had a very rare home cart release. In a few cases, conversions are made with EPROMs instead of Mask ROMs. Discussion is often a very touchy subject and thus information is not widely known on their creation. <br />
<br />
Generally, the value of a conversion is determined by the cost of parts (MVS cartridge, donor AES cart and label/insert) and not much more. Mask ROM conversions are usually worth only a fraction of an authentic NGH/AES copy. Ones made from EPROMs are worth considerably less. Conversions made from MVS exclusives are sometimes worth a bit more. <br />
<br />
In recent years, NGH/AES conversions have become increasingly advanced and near-identical to their authentic counterparts. So much that in some cases, the only way to distinguish between a conversion and an authentic copy is to have both on hand to meticulously compare. As a result the NGH/AES collector's market has become increasingly dangerous. Potential buyers are always highly encouraged to research a particular copy's history and integrity before they buy.<br />
<br />
On a related footnote, while often labeled as a stereotype, France has been accused and blamed for spearheading the advancement of conversions over the years. Some allegations against respected French collectors tend to be unfounded, while other cases have been proven with evidence. <br />
<br />
=== Freaked Cartridges=== <br />
<br />
A directly related subset of the home cartridges market, freaked cartridges are NGH/AES games that have been damaged in any number of ways by illegal distribution outfit Neo Geo Freak. The type of damage ranges from light cases of the occasional NGF sticker and re-printed case insert, to extreme examples of void stickers being plastered on the insert, cartridge and manual pages. The reasoning behind such damage isn't well known. <br />
<br />
In today's market, freaked cartridges are not very common and hardly change hands, likely from the drop in perceived value. Freaked carts with only a reprinted insert aren't worth much less than a legit copy, while horrifically freaked cartridges are always valued much less than pristine equivalents. <br />

<br />
A popular facet of the Neo Geo that has grown over the years is the practice of modding NGH hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the Neo Geo. Commonly installed mods include: <br />
<br />
* S-Video (using the original Sony CXA1145 video encoder)<br />
* Component (using a new video encoder)<br />
* Universe BIOS (replacing the original stock BIOS<br />
* Debug BIOS (made obsolete by the Universe BIOS)<br />
* RGB Bypass (used to increase RGB video output fidelity)<br />
* Power LED (typically installed inside the reset button)<br />
* Replacement controller buttons/joystick (typically performed on Old Style sticks, sometimes HORI sticks)<br />
<br />
Most fan modding is done by individuals for their own personal use, though some people do it as a service. Popular service providers include:<br />

<br />
The MVS (Multi Video System), as the Neo Geo was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-slot, 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />

== Collecting ==<br />
<br />
=== Loose Cartridges ===<br />
<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies. <br />
<br />
== Modification ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

<hr />
<div>The '''Neo Geo''' (ネオジオ) (officially printed as NEO•GEO) is a cartridge-based arcade and home video game system released on July 1, 1991 by Japanese game company SNK. Being in the Fourth generation of Gaming, it was the first console in the former Neo Geo family, which only lived through the 1990s. The hardware featured comparatively colourful 2D graphics. It's arcade counterpart is the [[Neo Geo MVS Arcade System]].<br />
<br />
The Neo Geo system was marketed as a very costly home console, commonly referred to today as the AES (Advanced Entertainment System). The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 16-bit system with an 8-bit Zilog Z80 as coprocessor. The coprocessor was used as a CPU, and for sound processing. The Super Nintendo and Sega Genesis also had similar co-processors, with neither Sega nor Nintendo claiming they were 24-bit.<br />
<br />
== History ==<br />
<br />
[[Image:Home_cart_system.jpg|300px|thumb|right]]<br />
<br />
Initially, the (AES) home system was only available for rent to commercial establishments, such as hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a $650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January, 1990 in Osaka, Japan. Compared to the other 16-bit consoles of the time, Neo Geo's graphics and sound were vastly superior. The MVS was one of the most powerful arcade units at the time. Furthermore, since the AES was identical to its arcade counterpart, the MVS, arcade titles released for the home market were perfect translations. Although its high price tag kept it out of the mainstream gaming market, a strong game lineup likely contributed to the cult status of the Neo Geo, enabling it to outlast the more popular Sega Mega Drive/Genesis.<br />
<br />
In the United States, the console was planned to debut at $599 USD and included two joystick controllers and a game, either Baseball Stars Professional or NAM-1975. However, the price was raised and its American launch debuted at $649.99. This package was known as the "Gold System." Later, the "Gold System" was bundled with Magician Lord and Fatal Fury. The system was also released in a "Silver System" package for $399.99, which included one joystick controller and did not include a game. Other games were priced at about $200 (and up). With these "premium" prices, though, most gamers weren't able to afford the system, so the console was only accessible to a niche market.<br />
<br />
The home system featured two CPUs: the 16-bit Motorola 68000 main processor running at 12 MHz and the 8-bit Zilog Z80 coprocessor running at 4 MHz. A custom video chipset allowed the system to display 4,096 colors and 380 individual sprites onscreen simultaneously, while the onboard Yamaha YM2610 sound chip gave the system 15 channels of sound with seven channels reserved specifically for digital sound effects. When realtime 3D graphics stormed the arcade industry, the Neo Geo's hardware was unable to follow along. The longevity of Neo Geo games kept it alive in arcades, particularly in Japan, where the newest installment of its flagship franchise, The King of Fighters, caused a stir with every new release.<br />
<br />
The last official game by SNK for the Neo Geo system, Samurai Shodown V Special, was released in 2004. SNK decided to abandon the video game hardware business due to the rampant piracy of game-cartridges, which SNK believed was partially responsible for its bankruptcy in 2001. SNK ceased to manufacture home consoles by the end of 1997, but continued to release games for both arcade and home for another 8 years.<br />
<br />
Measured from the introduction of the arcade hardware in 1990 to the release of the last official home cartridge in 2004, the Neo Geo enjoyed a market lifespan of fourteen years, making it the second longest-lived arcade or home console system ever produced (after Atari 2600). On August 31, 2007, SNK stopped offering maintenance and repairs to Neo Geo home consoles, handhelds, and games. However, they will continue to repair their MVS arcade hardware.<br />
<br />
<center>[[Image:Neo-Geo-AES-Console-Set-small.png|600px]]</center><br />
<br />
== Technical Aspects ==<br />
<br />
Each joystick controller was 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × 2.5 in.) and contained the same four-button layout as the arcade MVS cabinet.<br />
<br />
The arcade machines had a memory card system by which a player could save a game to return to at a later time and could also be used to continue play on the SNK home console of the same name.<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!".

<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />
=== Graphics ===<br />
<br />
Unlike most other video game consoles of its time, the Neo Geo did not use tilemap background layers. Instead, it relied exclusively on drawing sprites to create the background. Sprites are vertical strips which are 16 pixels wide, and can be 16 to 512 pixels tall. By laying multiple sprites side by side, the system can simulate a background layer. The system can draw up to 384 sprites on the screen at a time, and up to 96 per scanline.<br />

<br />
=== Home Cartridges ===<br />
<br />
There is a thriving collector's scene for the Neo Geo home systems, especially the original AES home console. This is mainly because of the limited runs received by cartridges, the massive arcade library available, and the system's reputation as a 2D powerhouse. It is still common even to this day for both Neo Geo consoles and cartridges to fetch extremely high prices on eBay and other auction websites, particularly English versions of cartridges as these were produced in lower quantities. A handful of the rarest Neo Geo games can sell for well over $1,000 on eBay. This gives the system an almost cult following, as owners see the system as more of an "investment" rather than an ordinary videogame console. This leads to high resale value on most Neo Geo systems and games and makes the console a "must-have" for a number of video game collectors. The most expensive cartridge for the Neo Geo home system is the European-localized version of Kizuna Encounter: There are only five known copies of the game, with the most recently sold copy selling for about $12,000 USD.<br />
<br />
=== Conversions === <br />
<br />
Conversions are NGH/AES cartridges that have had their original Mask ROMs removed and replaced with those of an MVS cartridge, typically from an MVS game which had no home cart release, or sometimes one that had a very rare home cart release. In a few cases, conversions are made with EPROMs instead of Mask ROMs. Discussion is often a very touchy subject and thus information is not widely known on their creation. <br />
<br />
Generally, the value of a conversion is determined by the cost of parts (MVS cartridge, donor AES cart and label/insert) and not much more. Mask ROM conversions are usually worth only a fraction of an authentic NGH/AES copy. Ones made from EPROMs are worth considerably less. Conversions made from MVS exclusives are sometimes worth a bit more. <br />
<br />
In recent years, NGH/AES conversions have become increasingly advanced and near-identical to their authentic counterparts. So much that in some cases, the only way to distinguish between a conversion and an authentic copy is to have both on hand to meticulously compare. As a result the NGH/AES collector's market has become increasingly dangerous. Potential buyers are always highly encouraged to research a particular copy's history and integrity before they buy.<br />
<br />
On a related footnote, while often labeled as a stereotype, France has been accused and blamed for spearheading the advancement of conversions over the years. Some allegations against respected French collectors tend to be unfounded, while other cases have been proven with evidence. <br />
<br />
=== Freaked Cartridges=== <br />
<br />
A directly related subset of the home cartridges market, freaked cartridges are NGH/AES games that have been damaged in any number of ways by illegal distribution outfit Neo Geo Freak. The type of damage ranges from light cases of the occasional NGF sticker and re-printed case insert, to extreme examples of void stickers being plastered on the insert, cartridge and manual pages. The reasoning behind such damage isn't well known. <br />
<br />
In today's market, freaked cartridges are not very common and hardly change hands, likely from the drop in perceived value. Freaked carts with only a reprinted insert aren't worth much less than a legit copy, while horrifically freaked cartridges are always valued much less than pristine equivalents. <br />
<br />
== Modding ==<br />
<br />
[[Image:Modded_neo_geo2.jpg|300px|thumb|right|A Neo Geo console modded with Composite, S-Video, Component and Stereo Sound]]<br />
<br />
A popular facet of the Neo Geo that has grown over the years is the practice of modding NGH hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the Neo Geo. Commonly installed mods include: <br />
<br />
* S-Video (using the original Sony CXA1145 video encoder)<br />
* Component (using a new video encoder)<br />
* Universe BIOS (replacing the original stock BIOS<br />
* Debug BIOS (made obsolete by the Universe BIOS)<br />
* RGB Bypass (used to increase RGB video output fidelity)<br />
* Power LED (typically installed inside the reset button)<br />
* Replacement controller buttons/joystick (typically performed on Old Style sticks, sometimes HORI sticks)<br />
<br />
Most fan modding is done by individuals for their own personal use, though some people do it as a service. Popular service providers include:<br />

<div>The '''Neo Geo''' (ネオジオ) (officially printed as NEO•GEO) is a cartridge-based arcade and home video game system released on July 1, 1991 by Japanese game company SNK. Being in the Fourth generation of Gaming, it was the first console in the former Neo Geo family, which only lived through the 1990s. The hardware featured comparatively colourful 2D graphics. It's arcade counterpart is the [[Neo Geo MVS Arcade System]].<br />
<br />
The Neo Geo system was marketed as a very costly home console, commonly referred to today as the AES (Advanced Entertainment System). The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 16-bit system with an 8-bit Zilog Z80 as coprocessor. The coprocessor was used as a CPU, and for sound processing. The Super Nintendo and Sega Genesis also had similar co-processors, with neither Sega nor Nintendo claiming they were 24-bit.<br />
<br />
== History ==<br />
<br />
[[File:Home cart system.jpg|300px|thumb|right]]<br />
<br />
Initially, the (AES) home system was only available for rent to commercial establishments, such as hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a $650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January, 1990 in Osaka, Japan. Compared to the other 16-bit consoles of the time, Neo Geo's graphics and sound were vastly superior. The MVS was one of the most powerful arcade units at the time. Furthermore, since the AES was identical to its arcade counterpart, the MVS, arcade titles released for the home market were perfect translations. Although its high price tag kept it out of the mainstream gaming market, a strong game lineup likely contributed to the cult status of the Neo Geo, enabling it to outlast the more popular Sega Mega Drive/Genesis.<br />
<br />
In the United States, the console was planned to debut at $599 USD and included two joystick controllers and a game, either Baseball Stars Professional or NAM-1975. However, the price was raised and its American launch debuted at $649.99. This package was known as the "Gold System." Later, the "Gold System" was bundled with Magician Lord and Fatal Fury. The system was also released in a "Silver System" package for $399.99, which included one joystick controller and did not include a game. Other games were priced at about $200 (and up). With these "premium" prices, though, most gamers weren't able to afford the system, so the console was only accessible to a niche market.<br />
<br />
The home system featured two CPUs: the 16-bit Motorola 68000 main processor running at 12 MHz and the 8-bit Zilog Z80 coprocessor running at 4 MHz. A custom video chipset allowed the system to display 4,096 colors and 380 individual sprites onscreen simultaneously, while the onboard Yamaha YM2610 sound chip gave the system 15 channels of sound with seven channels reserved specifically for digital sound effects. When realtime 3D graphics stormed the arcade industry, the Neo Geo's hardware was unable to follow along. The longevity of Neo Geo games kept it alive in arcades, particularly in Japan, where the newest installment of its flagship franchise, The King of Fighters, caused a stir with every new release.<br />
<br />
The last official game by SNK for the Neo Geo system, Samurai Shodown V Special, was released in 2004. SNK decided to abandon the video game hardware business due to the rampant piracy of game-cartridges, which SNK believed was partially responsible for its bankruptcy in 2001. SNK ceased to manufacture home consoles by the end of 1997, but continued to release games for both arcade and home for another 8 years.<br />
<br />
Measured from the introduction of the arcade hardware in 1990 to the release of the last official home cartridge in 2004, the Neo Geo enjoyed a market lifespan of fourteen years, making it the second longest-lived arcade or home console system ever produced (after Atari 2600). On August 31, 2007, SNK stopped offering maintenance and repairs to Neo Geo home consoles, handhelds, and games. However, they will continue to repair their MVS arcade hardware.<br />
<br />

<br />
== Technical Aspects ==<br />
<br />
Each joystick controller was 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × 2.5 in.) and contained the same four-button layout as the arcade MVS cabinet.<br />
<br />
The arcade machines had a memory card system by which a player could save a game to return to at a later time and could also be used to continue play on the SNK home console of the same name.<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />
=== Graphics ===<br />
<br />
Unlike most other video game consoles of its time, the Neo Geo did not use tilemap background layers. Instead, it relied exclusively on drawing sprites to create the background. Sprites are vertical strips which are 16 pixels wide, and can be 16 to 512 pixels tall. By laying multiple sprites side by side, the system can simulate a background layer. The system can draw up to 384 sprites on the screen at a time, and up to 96 per scanline.<br />

== Collecting ==<br />

<br />
=== Home Cartridges ===<br />
<br />
There is a thriving collector's scene for the Neo Geo home systems, especially the original AES home console. This is mainly because of the limited runs received by cartridges, the massive arcade library available, and the system's reputation as a 2D powerhouse. It is still common even to this day for both Neo Geo consoles and cartridges to fetch extremely high prices on eBay and other auction websites, particularly English versions of cartridges as these were produced in lower quantities. A handful of the rarest Neo Geo games can sell for well over $1,000 on eBay. This gives the system an almost cult following, as owners see the system as more of an "investment" rather than an ordinary videogame console. This leads to high resale value on most Neo Geo systems and games and makes the console a "must-have" for a number of video game collectors. The most expensive cartridge for the Neo Geo home system is the European-localized version of Kizuna Encounter: There are only five known copies of the game, with the most recently sold copy selling for about $12,000 USD.<br />
<br />
=== Conversions === <br />
<br />
Conversions are NGH/AES cartridges that have had their original Mask ROMs removed and replaced with those of an MVS cartridge, typically from an MVS game which had no home cart release, or sometimes one that had a very rare home cart release. In a few cases, conversions are made with EPROMs instead of Mask ROMs. Discussion is often a very touchy subject and thus information is not widely known on their creation. <br />
<br />
Generally, the value of a conversion is determined by the cost of parts (MVS cartridge, donor AES cart and label/insert) and not much more. Mask ROM conversions are usually worth only a fraction of an authentic NGH/AES copy. Ones made from EPROMs are worth considerably less. Conversions made from MVS exclusives are sometimes worth a bit more. <br />
<br />
In recent years, NGH/AES conversions have become increasingly advanced and near-identical to their authentic counterparts. So much that in some cases, the only way to distinguish between a conversion and an authentic copy is to have both on hand to meticulously compare. As a result the NGH/AES collector's market has become increasingly dangerous. Potential buyers are always highly encouraged to research a particular copy's history and integrity before they buy.<br />
<br />
On a related footnote, while often labeled as a stereotype, France has been accused and blamed for spearheading the advancement of conversions over the years. Some allegations against respected French collectors tend to be unfounded, while other cases have been proven with evidence. <br />
<br />
=== Freaked Cartridges=== <br />
<br />
A directly related subset of the home cartridges market, freaked cartridges are NGH/AES games that have been damaged in any number of ways by illegal distribution outfit Neo Geo Freak. The type of damage ranges from light cases of the occasional NGF sticker and re-printed case insert, to extreme examples of void stickers being plastered on the insert, cartridge and manual pages. The reasoning behind such damage isn't well known. <br />
<br />
In today's market, freaked cartridges are not very common and hardly change hands, likely from the drop in perceived value. Freaked carts with only a reprinted insert aren't worth much less than a legit copy, while horrifically freaked cartridges are always valued much less than pristine equivalents. <br />
<br />
== Modding ==<br />
<br />
[[File:Modded neo geo2.jpg|300px|thumb|right|A Neo Geo console modded with composite, S-Video, Component and Stereo Sound]]<br />
<br />
A popular facet of the Neo Geo that has grown over the years is the practice of modding NGH hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the Neo Geo. Commonly installed mods include: <br />
<br />
* S-Video (using the original Sony CXA1145 video encoder)<br />
* Component (using a new video encoder)<br />
* Universe BIOS (replacing the original stock BIOS<br />
* Debug BIOS (made obsolete by the Universe BIOS)<br />
* RGB Bypass (used to increase RGB video output fidelity)<br />
* Power LED (typically installed inside the reset button)<br />
* Replacement controller buttons/joystick (typically performed on Old Style sticks, sometimes HORI sticks)<br />
<br />
Most fan modding is done by individuals for their own personal use, though some people do it as a service. Popular service providers include:<br />
<br />
* Xian Xi (frequents Neo-Geo.com and runs Jamma Nation X)<br />
* JMKurtz <br />
* kpj (operates Neotropolis)<br />

<br />
The MVS (Multi Video System), as the Neo Geo was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-slot, 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />

== Collecting ==<br />
<br />
=== Loose Cartridges ===<br />
<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies. <br />
<br />
== Modding ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

<hr />
<div>The '''Neo Geo''' (ネオジオ) (officially printed as NEO•GEO) is a cartridge-based arcade and home video game system released on July 1, 1991 by Japanese game company SNK. Being in the Fourth generation of Gaming, it was the first console in the former Neo Geo family, which only lived through the 1990s. The hardware featured comparatively colourful 2D graphics. It's arcade counterpart is the [[Neo Geo MVS Arcade System]].<br />
<br />
The Neo Geo system was marketed as a very costly home console, commonly referred to today as the AES (Advanced Entertainment System). The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 16-bit system with an 8-bit Zilog Z80 as coprocessor. The coprocessor was used as a CPU, and for sound processing. The Super Nintendo and Sega Genesis also had similar co-processors, with neither Sega nor Nintendo claiming they were 24-bit.<br />
<br />
== History ==<br />
<br />
Initially, the (AES) home system was only available for rent to commercial establishments, such as hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a $650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January, 1990 in Osaka, Japan. Compared to the other 16-bit consoles of the time, Neo Geo's graphics and sound were vastly superior. The MVS was one of the most powerful arcade units at the time. Furthermore, since the AES was identical to its arcade counterpart, the MVS, arcade titles released for the home market were perfect translations. Although its high price tag kept it out of the mainstream gaming market, a strong game lineup likely contributed to the cult status of the Neo Geo, enabling it to outlast the more popular Sega Mega Drive/Genesis.<br />
<br />
In the United States, the console was planned to debut at $599 USD and included two joystick controllers and a game, either Baseball Stars Professional or NAM-1975. However, the price was raised and its American launch debuted at $649.99. This package was known as the "Gold System." Later, the "Gold System" was bundled with Magician Lord and Fatal Fury. The system was also released in a "Silver System" package for $399.99, which included one joystick controller and did not include a game. Other games were priced at about $200 (and up). With these "premium" prices, though, most gamers weren't able to afford the system, so the console was only accessible to a niche market.<br />
<br />
The home system featured two CPUs: the 16-bit Motorola 68000 main processor running at 12 MHz and the 8-bit Zilog Z80 coprocessor running at 4 MHz. A custom video chipset allowed the system to display 4,096 colors and 380 individual sprites onscreen simultaneously, while the onboard Yamaha YM2610 sound chip gave the system 15 channels of sound with seven channels reserved specifically for digital sound effects. When realtime 3D graphics stormed the arcade industry, the Neo Geo's hardware was unable to follow along. The longevity of Neo Geo games kept it alive in arcades, particularly in Japan, where the newest installment of its flagship franchise, The King of Fighters, caused a stir with every new release.<br />
<br />
The last official game by SNK for the Neo Geo system, Samurai Shodown V Special, was released in 2004. SNK decided to abandon the video game hardware business due to the rampant piracy of game-cartridges, which SNK believed was partially responsible for its bankruptcy in 2001. SNK ceased to manufacture home consoles by the end of 1997, but continued to release games for both arcade and home for another 8 years.<br />
<br />
Measured from the introduction of the arcade hardware in 1990 to the release of the last official home cartridge in 2004, the Neo Geo enjoyed a market lifespan of fourteen years, making it the second longest-lived arcade or home console system ever produced (after Atari 2600). On August 31, 2007, SNK stopped offering maintenance and repairs to Neo Geo home consoles, handhelds, and games. However, they will continue to repair their MVS arcade hardware.<br />

<br />
== Technical Aspects ==<br />
<br />
Each joystick controller was 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × 2.5 in.) and contained the same four-button layout as the arcade MVS cabinet.<br />
<br />
The arcade machines had a memory card system by which a player could save a game to return to at a later time and could also be used to continue play on the SNK home console of the same name.<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />
<br />
In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />
<br />
=== Graphics ===<br />
<br />
Unlike most other video game consoles of its time, the Neo Geo did not use tilemap background layers. Instead, it relied exclusively on drawing sprites to create the background. Sprites are vertical strips which are 16 pixels wide, and can be 16 to 512 pixels tall. By laying multiple sprites side by side, the system can simulate a background layer. The system can draw up to 384 sprites on the screen at a time, and up to 96 per scanline.<br />

== Collecting ==<br />
<br />
=== Home Cartridges ===<br />
<br />
There is a thriving collector's scene for the Neo Geo home systems, especially the original AES home console. This is mainly because of the limited runs received by cartridges, the massive arcade library available, and the system's reputation as a 2D powerhouse. It is still common even to this day for both Neo Geo consoles and cartridges to fetch extremely high prices on eBay and other auction websites, particularly English versions of cartridges as these were produced in lower quantities. A handful of the rarest Neo Geo games can sell for well over $1,000 on eBay. This gives the system an almost cult following, as owners see the system as more of an "investment" rather than an ordinary videogame console. This leads to high resale value on most Neo Geo systems and games and makes the console a "must-have" for a number of video game collectors. The most expensive cartridge for the Neo Geo home system is the European-localized version of Kizuna Encounter: There are only five known copies of the game, with the most recently sold copy selling for about $12,000 USD.<br />
<br />
=== Conversions === <br />
<br />
Conversions are NGH/AES cartridges that have had their original Mask ROMs removed and replaced with those of an MVS cartridge, typically from an MVS game which had no home cart release, or sometimes one that had a very rare home cart release. In a few cases, conversions are made with EPROMs instead of Mask ROMs. Discussion is often a very touchy subject and thus information is not widely known on their creation. <br />
<br />
Generally, the value of a conversion is determined by the cost of parts (MVS cartridge, donor AES cart and label/insert) and not much more. Mask ROM conversions are usually worth only a fraction of an authentic NGH/AES copy. Ones made from EPROMs are worth considerably less. Conversions made from MVS exclusives are sometimes worth a bit more. <br />
<br />
In recent years, NGH/AES conversions have become increasingly advanced and near-identical to their authentic counterparts. So much that in some cases, the only way to distinguish between a conversion and an authentic copy is to have both on hand to meticulously compare. As a result the NGH/AES collector's market has become increasingly dangerous. Potential buyers are always highly encouraged to research a particular copy's history and integrity before they buy.<br />
<br />
On a related footnote, while often labeled as a stereotype, France has been accused and blamed for spearheading the advancement of conversions over the years. Some allegations against respected French collectors tend to be unfounded, while other cases have been proven with evidence. <br />
<br />
=== Freaked Cartridges=== <br />
<br />
A directly related subset of the home cartridges market, freaked cartridges are NGH/AES games that have been damaged in any number of ways by illegal distribution outfit Neo Geo Freak. The type of damage ranges from light cases of the occasional NGF sticker and re-printed case insert, to extreme examples of void stickers being plastered on the insert, cartridge and manual pages. The reasoning behind such damage isn't well known. <br />
<br />
In today's market, freaked cartridges are not very common and hardly change hands, likely from the drop in perceived value. Freaked carts with only a reprinted insert aren't worth much less than a legit copy, while horrifically freaked cartridges are always valued much less than pristine equivalents. <br />
<br />
== Modding ==<br />
<br />
A popular facet of the Neo Geo that has grown over the years is the practice of modding NGH hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the Neo Geo. Commonly installed mods include: <br />
<br />
* S-Video (using the original Sony CXA1145 video encoder)<br />
* Component (using a new video encoder)<br />
* Universe BIOS (replacing the original stock BIOS<br />
* Debug BIOS (made obsolete by the Universe BIOS)<br />
* RGB Bypass (used to increase RGB video output fidelity)<br />
* Power LED (typically installed inside the reset button)<br />
* Replacement controller buttons/joystick (typically performed on Old Style sticks, sometimes HORI sticks)<br />
<br />
Most fan modding is done by individuals for their own personal use, though some people do it as a service. Popular service providers include:<br />
<br />
* Xian Xi (frequents Neo-Geo.com and runs Jamma Nation X)<br />
* JMKurtz <br />
* kpj (operates Neotropolis)<br />

<br />
The MVS (Multi Video System), as the Neo Geo was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform. It's home counterpart is the [[Neo Geo Home System]]<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
<br />
== Technical Aspects ==<br />
<br />
The arcade version of the video game hardware is often referred to as the "MVS," or Multi Video System (available in 1-slot, 2-slot, 4-slot, and 6-slot variations, the latter being capable of up to six cartridges loaded into one machine), with its console counterpart unofficially referred to as the "AES", or Advanced Entertainment System (most likely because SNK USA marketed the Neo Geo with that term, most commonly seen printed in gold text on all home systems).<br />
<br />
The MVS and AES hardware could execute identical machine code. Owners could move Mask ROMs from one type to the other, and the game would still run. The program specifics for both MVS and AES game options were contained on every game ROM, whether the cartridge was intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.<br />
<br />
=== ROM sizes and startup screens ===<br />
<br />
Specification for ROM size was up to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" upon startup. While no technical advances were required to achieve it, some games over 100 megabits, such as [[World Heroes 2]], followed this screen by displaying an animation proclaiming "THE 100MEGA SHOCK!". The original ROM size spec was later enhanced on cartridges with bank switching memory technology, increasing the maximum cartridge size to 716 Mbit. These new cartridges also caused the system to display "GIGA POWER PRO-GEAR SPEC" upon startup, indicating this enhancement.<br />
<br />
[[File:Neogeo 100megashock.png]] [[File:GigaPower.png]]<br />

In recent years, advances in modern technology and the ever dropping price in ROM memory, unofficial homebrew games like [[Fast Striker]] are well over 1Gbit in size. <br />

== Collecting ==<br />
<br />
=== Loose Cartridges ===<br />
<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies. <br />
<br />
== Modding ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

== Collecting ==<br />
<br />
=== Loose Arcade cartridges ===<br />
<br />
MVS cartridges were initially designed for arcade use, but over the years a strong market has developed around collecting this particular format.<br />
<br />
For those interested primarily in lower prices on rare home games, MVS carts, particularly loose carts or incomplete kits, can offer a cost effective alternative. Most MVS cartridges cost substantially less than their home counterparts. This lower price can be associated with their lack of decoration as most were designed to be installed inside arcade cabinets and lack cartridge artwork or box artwork, the high set-up cost of purchasing the MVS system, and the prevalence of bootleg cartridges. Many of the most common MVS games go for prices between $10–$150.<br />
<br />
=== Complete Kits ===<br />
<br />
In recent years a growing market has emerged for complete MVS arcade kits. These consist of all the materials that would be initially sent to an arcade operator, including the brown cardboard shipping box (with label), the insert materials to decorate the marqee and arcade cabinet (including separate move lists), warning information, dipswitch settings, in some cases even posters and/or any packing materials. Because many of the items in an MVS kit were designed to be discarded by arcade operators, finding complete arcade kits can be difficult and thus the prices for some complete MVS kits can be quite high.<br />
<br />
=== Bootlegs ===<br />
<br />
Counterfeit or bootleg software is regarded in the collectors community as having zero value or very low value. Such software has a reputation for audio and video flaws, and is generally disparaged by fans of the Neo Geo systems. This software is identifiable by visual inspection of the game PCBs, or by comparison of ROM CRC values using a specially designed BIOS.<br />
<br />
Within the MVS collector's market, bootlegs are commonly found and can sometimes be mistaken for legit copies, or intentionally used to scam people into thinking they are legit. However, unlike modern conversions in the home cart market, bootlegs are very rarely near-identical to their authentic counterparts. If opened, bootlegs are tend to have one or more easily identifiable flaws that separate them from legit copies. <br />
<br />
== Modding ==<br />
<br />
A popular facet of the MVS that has grown over the years, even surpassing that of the Neo Geo NGH/AES system, is the practice of modding MVS hardware. Virtually all of the mainstay mods enhance or replace certain original functions of the MVS. Mods to plain MVS boards (for use in cabinets) are not numerous, such mods include:<br />
<br />
* Universe BIOS (replacing the original stock BIOS)<br />
* Overclock (uncommonly performed, tends to cause incompatibility with certain titles)<br />
<br />
=== Consolization === <br />
<br />
[[File:Omegasystem.png|300px|thumb|right|The Omega Neo Geo CMVS]]<br />
<br />
Above all, the most popular modification available to MVS, is consolization. The term describes the process of installing several individual mods into an MVS board that convert it into a home console. Possible mods and features of an Consolized MVS include: <br />
<br />
* S-Video<br />
* Component Video<br />
* Stereo Sound (some MVS boards don't easily output stereo and require a modification)<br />
* Universe BIOS<br />
* Controller ports<br />
* Power jack (usually for a 5 volt AC adapter, in conjunction with a 5v only mod)<br />
* Power LED<br />
* Custom PCB shell (or sometimes the board's original shell is used)<br />
<br />
In recent time, high end CMVS units have become increasingly popular. Two very notable examples include the Analogue Interactive Wooden CMVS and the Omega CMVS. <br />

<br />
The MVS (Multi Video System), as the Neo Geo was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform.<br />
<br />
== History ==<br />
<br />
[[Image:Neogeoguts.JPG|thumb|left|200px]]<br />
<br />
During 1988 SNK began toying with the idea of a modular cabinet for arcades; up to that point, arcade cabinets typically contained only a single game. When an arcade operator wanted to switch or replace that game, they would have to completely remove the internals of the existing cabinet or exchange the entire setup for another game. SNK's new system, called Neo-Geo MVS (short for Multi-Video System), featured multiple games in a single cabinet and used a cartridge-based storage mechanism. The system debuted in 1990 and could contain one, two, four, or six separate games in a single cabinet. In order to swap in a new game, all the operator had to do was remove one cartridge and exchange it for another. The MVS was an immediate success. Arcade operators loved it because the setup time required for each game was nearly nonexistent, the floor space required was minimal, and the cost outlay for new cartridges was barely $500—less than half of what a traditional arcade unit cost at the time.<br />
