Playing Neo Geo CD titles at full speed :)

yoko kurama · May 2, 2009

Not sure how many of you guys are familiar with modding out your XBOX with different firmware and replacing the reader with a Samsung 616T disk reader....but I picked up a modded Xbox not too long ago......mine is flashed with firmware and has the ability to play originals or burns from these systems:

Neo Geo CD
Sega CD
Turbo Grafx 16 / PC Engine / Turbo Duo
Playstation 1 (These games have to be imaged to HDD)

Anyways for all the pain of having to play the NGCD games in slow motion and wait like 5 mins between loads - figured for those who did not know

Easy way to play them at full speed and actually enjoy playing them

Huh... no shit. Didn't even know that was possible. Do you have any knowledge of how to go about doing that?

yoko kurama · May 2, 2009

I wish - I have the loader and the original game (mechassault) to soft mod the systems with - but I have never used it or done it....my buddy has a friend that does it.....plus I have a friend at work that does it - he is actually upgrading the Firmware on my 360 right now so I can play UFC 2009

You know if you've got your Xbox modded, you can just slap MAME on it. I don't see the point of this.

yoko kurama · May 2, 2009

I have MAME on my xbox - but it does not always play the port of the game like the real deal - I have played several games from the MVS/AES and Atomiswave on my XBOX - but there is not a mame of the NGCD's that I have found as of yet, so I just play them on my xbox and they load so muc faster and play hell of alot smoother on the xbox - that's why I am getting rid of my Neo Geo cd unit's - I don't even touch them since I picked up this xbox.

Just like the NGCD emus available on Xbox.

That's why this thread IMO doesn't really make sense.

yoko kurama · May 2, 2009

The point was not about playing MAME! The point was being able to pay the ORIGINAL or BACKUPS of the Neo Geo CD Games at full speed instead of waiting for the downloads from hell with the slow ass 1x and 2x readers the NGCD systems have.

Takumaji · May 2, 2009

Yeah I'm aware of that.

Thing is - with the advantage of much faster loading of NGCD originals or backups on Xbox comes the disadvantage of improper or downright buggy NGCD emulation.

That's why I think this doesn't make sense because you'll only replace on evil with another.

Better stick to the original hardware if you want to play the games like they were meant to be played or get a CMVS or homecart system if you don't want to wait for CD-based games to load.

Mind you, I'm not against emulation per se, I just dabbled with Xbox emu long enough to know its limits.

NEO CD emulation is always going to be at most on par with MAME.

joe8 · May 2, 2009

Emulation is not done at hardware level (eg MAME currently only emulates at Logical level- there are three levels of emulation(in descending order of accuracy)- Signal level, Logical level, HLE (High Level Emulation). Even the simplest games would run at much less than normal speed, if emulated at signal level.
So to do perfect emulation of the Neo Geo AES/MVS/CD would require Signal level emulation, which probably won't be possible for many years.
The Neo Geo CD has the same hardware as the AES/MVS (eg 68000, Z80, custom chips), that's why it's versions of the games are so accurate. It can run the same code in the same way. The Neo was one of the more difficult systems to emulate, because of it's multiple processors (including the custom chips) and it's direct ROM access feature(requiring a newer PC with 64 or 128Mb of RAM). So it would be even harder to emulate at Signal level than other arcade systems with only one CPU.

yoko kurama · May 2, 2009

Now I agree with Joe8 on it being one of the harder ones to emulate lol - and of course there is a fault in all emulators of some sort. But one system that no one has been able to emulate yet is the Saturn - I have so many games burned for that system and no way to play them

- I will eventually find another modded Saturn or get my hands on some Modchips that are worth a crap lol

^ the saturn has been emulated already, just look for SSF emulator for the PC.

runs like poop though, doesn't it?

Runs perfect for me, my PC specs are nothing special:
DFI Lan Party X48
e8400
2x 1GB 4850 in Crossfire
4GB RAM

Edit:
I'm using version 010_alpha_R3

yoko kurama · May 3, 2009

Hmmm I'll have to look for it on PC - I know it has not been emulated for any system like xbox or anything - the systems can't run SS emulation because of the Saturn's precessor set...but PC might be cool

Might be worth making a MAME cab lol

Wow I'm impressed! Check this out:

I'd say you need a "fairly beefy" or at least modern / up to date pc to run at "full speed". None of these old spare PCs like when you're building a simple MAME box. Spec taken from the SSF website:

What requirements do I need to run SSF?

All Saturn emulators need a fairly beefy PC to run due to the complexity of the hardware they emulate.

Hardware:

CPU - At least a Pentium 4 3.2Ghz or AMD64. SSF cannot run on a Pentium 3, Duron, Athlon XP or 32bit Semprons (Socket A) due to requiring SSE2 instructions not available in these and older CPUs. A Core 2 Duo E6300 is recommended for full-speed.

Sound card - Most modern sound chips should work fine. Realtek High Definition audio (built into many motherboards) is known to work well.

Graphics card - A fast Direct X 9 compliant graphics card. The SSF author recommended at least a GeForce 6600GT and I too have verified this works perfectly even the AGP version. In theory an ATI/AMD Radeon 9800 should also be fine but I am unable to test this. Intel graphics built in to many laptops and motherboards are too slow to run SSF properly.

CD-ROM drive - 8x speed ATAPI compliant minimum. Any modern IDE CD,DVD,HD-DVD or even Blu-ray drive should work. Some Blu-ray drives do not support CDs however so bear that in mind. Note that it IS possible to make copies of Saturn CDs and burn them onto DVDs (for example if your drive will not read CDs but you have a friend who can do this for you) but you MUST own the original CD or else you are breaking the law.

Software:

Direct X - DirectX 9 is REQUIRED.

Windows 2000, Windows XP (all versions), Windows XP 64Bit Edition.
Why is SSF so slow?

Your PC isnt fast enough.

SSF is now able to emulate the Saturn full-speed if you meet the specifications listed above. If your PC DOES meet the above and it still runs slow you might have found an incompatible game, have problems with your graphics drivers, your graphics card or a misconfiguration of your PC.

Why does the Saturn need such a powerful PC? The following should put things into perspective:

Just tried the Sega Saturn emulator (SSF). Pretty damn amazing... was up and running in less than 5 minutes. The website even links all the bioses.

http://ssftribute.emuunlim.com/main.php

Grabbed the first original Saturn game (non-CDR) within reach (SF Zero 2) and it ran like a champ. The specs of the PC I tried this on:

Windows Vista Ultimate 32-bit
Intel Pentium Core2 Quad Q6600 @ 2.40 GHz
2 GB RAM
Nvidia GeForce 8300 GS
TSSTcorp DVD+-RW TS-H653B ATA

Now to dig out my Saturn shmups and tate the screen! :drool_2:

StealthLurker · May 3, 2009

Working great :lolz:

Rockin it on the 28" in TATE. Pics don't do it justice. Thanks for the Saturn emu heads up!

SSF is awesome, runs all of my games. I've been using it ever since my Pro Action Replay died.

Takumaji · May 3, 2009

Okay, since this is an general emu topic now I'll move it to Unrelated. Sit tight...

not sonic · May 3, 2009

the mame ive used on xbox runs really badly.

most xbox emus look pretty terrible (blurry, interlaced flicker, etc.)

Jedah Doma · May 3, 2009

Kawa X plays all of the games at full speed with no loading times whatsoever.
