Neo Geo CD Conversion Project.

[Metro City]

According to my information, Spin Master is working perfectly on the NeoGeo CDZ, as well as Eight Man. I have only tested the other games on an emulator, but this weekend I plan to burn some media and test them on the NeoGeo CDZ hardware.

I’ll leave here some port suggestions: games from SNK’s older boards, such as the SNK 68000 BASED HARDWARE, like Ikari III: The Rescue and SAR: Search and Rescue (although, due to the screen style, I’m not sure if it will be easy to port these). Another interesting board is the SNK PSYCHO SOLDIER HARDWARE, with games like Psycho Soldier. One game that has specs almost identical to the MVS is Prehistoric Isle in 1930, with a main CPU of 68000 @ 12 MHz, a sound CPU of Z80 @ 4 MHz, and sound chips YM3812 @ 4 MHz and UPD7759 @ 640 kHz.

To finish, something surprising: another game that uses the 6800 CPU and has a style very similar to NeoGeo is Power Instinct.

but, Prehistoric Isle? one of the snk arcade machines I saw and liked at the time.

Do you think something made @iq_132 upset with the people here, since he hasn't posted anything about the MVS to NeoGeo CD conversions anymore?

 

[NeoSeeD]

He might be taking a well-deserved break after porting a substantial amount of games in a very short time. He could also be working on a large project that takes a lot of time. There were a few games that he was working on and/or released for the MVS/AES that I hope he ports over to the CD someday.

• Cabal
• Soldier Girl Amazon
• Terra Cresta
• Karnov
• Kid no Hore Hore Daisakusen (Cratermaze)

No, he probably got fed up with idiots hassling him to produce more Neo CD games like a fucking performing monkey.

FFS.

A variety of things. Break, working on projects that are being a pain. I've got an MVS->CD conversion that's done other than figuring out why it doesn't boot sometimes on the CD.

Here's a new one:

Data East's Karnov.

https://www.neo-source.com/stuff/karnov_builder.zip

Please note that I've included the ability to build AES/MVS ROMs (in MAME format) in this.
If I don't see bootlegs pop up on Facebook market place or AliExpress in the next couple of months, I'll go back and release POW and Chelnov for MVS too.

Old emulated video:

There are couple of things I'm not happy with this one, but I don't feel like working on it any longer:
1. On console mode, it requires hitting the select button to coin - it'd be nice to have free play.
2. Saving high scores to sram/memcard.
3. The music quality isn't great (I suck at sound work).

 

[Burning Fight!!]

I wouldn't be too inclined to release my hard work for people to profit off of, either, so it's alright if you don't end up releasing them. A shame but it is what it is.

I need to get a kof95 from my infinite supply and burn some eproms for this, Karnov is great.

[lithy]

I'd love to see more MVS roms for these conversions, I'm hoping that stuff like that will be playable with the BackBit cart.

Cool work as always.

Glad to hear that you took a break after a marathon of releases.

Neo CD version works great on original hardware. I've only played the NES version in the past and so far this arcade version is tough but fun.

Regarding the MVS file... I converted it to a .neo for my Neo SD Pro and while it boots and seems to run perfect, I'm unable to actually play the game as select won't insert a coin for me. Anyone else experience this? It's my first time converting to .neo, so it could have been something that I did on my end.

That definitely does not sound like a .neo conversion issue. More likely related to your setup or your bios mode. AES or MVS?

I've tried both AES and MVS modes on both original hardware and MiSTer. No luck on either.

 

[Neo Alec]

I played Karnov for a while on my MV1FS with Unibios 4.0 in home mode with no issues.

@iq_132 Dude, you were able to build save states into this one? That's amazing!

What hardware are you using? MVS-1xx or AES? Your BIOS is Uni-bios 4.0 or?
@Neo Alec can you get it to coin in MVS mode?

 

[iq_132]

I'm hoping to get one of those (BackBit) carts. As it is, I don't have a flash cart and it makes testing on cart-based hardware extremely difficult (Burning EPROMs to test is no fun).
The nice people that have donated to my Patreon made my work for the NeoGeo CD possible, helping me fund a NeoGeo CD and NeoGeo CD SD Loader.

 

[Neo Alec]

What hardware are you using? MVS-1xx or AES? Your BIOS is Uni-bios 4.0 or?
@Neo Alec can you get it to coin in MVS mode?

@iq_132 Yes. I am able to add coins with the select button in both AES and MVS modes on Unibios 4.0. I've tested it on a 1-slot and 4-slot boards now.

@NeoSeeD Try toggling the "input crossing" option in the Unibios options.

I own a AES with Unibios 4.0.

I'll give this a try today.

 

[NeoSeeD]

@NeoSeeD Try toggling the "input crossing" option in the Unibios options.

I don't think that option is available on the AES console unibios. Even if I change the region settings to arcade, unibios only allows for "Game Softdip settings" instead of "General Settings".

The Unibios readme shows input crossing as MVS only unfortunately.

*Edit. Confirmed on MiSTer. Once I ran as MVS unibios, I was able to insert a coin. If I ran as AES unibios, even is set to arcade, a coin cannot be inserted.

The Main Menu
-------------
To navigate the UNIVERSE BIOS menu you will need to use player 1 controls,
button (A) is used as select, (C) to exit. Here is a list of all available
options along with a small description.

Region Settings
---------------
This is where you choose your region and operation mode of the BIOS. Any settings
made on this screen are permanently saved until you decide to change them.

General Settings (MVS only)
---------------------------
Like the region settings these setting are also saved until changed.

- Disable BootUp HW Test
This option forces the UNIVERSE BIOS to skip some hardware tests at power on,
it makes booting faster but you have no guarantee the system is in full working
order. This option is on by default.

- Disable In Game Menu
This option disables the in game menu when enabled.

- Disable Input Crossing
When enabled this option will disable the input crossing feature.

- Enable Cabinet Fixes
When enabled 1Up (A) and (B) buttons will act as game select buttons during attract
mode on multislot hardware. This option also registers a coin entered into a cab
with only one coin chute to the 2Up side if 2Up (START) is held down while coin is
inserted. Only works in ARCADE mode while 2 coin counters are drawn on screen.

- Disable Splash Screen
This option disables the splash screen at startup when enabled.

- Enable Arcade Protect
This setting is designed to allow the Universe Bios to be run easier in an arcade
environment. When enabled either the TEST MODE button must also be pressed or
hard DIP 1 must be ON for button codes at the splash screen to work. This setting
also forces the system to reset if a game should crash instead of giving an error.

Game SoftDIP Settings (AES only)
--------------------------------
Here you can change game settings like the amount of lives given per game, amount of
time rounds lasts or enable blood for example. Note that Soft DIP s are reset on
changing the country region so always select your region setup before editing any
soft DIP s.

Okay, it's an AES. I'll try it on my AES next.

It's ok the project manager says you can take a break
