Do you guys think it would be possible? I mean.. its pretty complex hardware, and the only good emulators for Neo Geo that I know of (not CD!!!) are on PC only.
Is Neo Geo Emulation Possible On The Gp2x?

It's well into the land of "highly unlikely" and making a run for the border of "impossible".
On paper it doesn't look that tough: A 12MHz 68000 CPU and a 4MHz Z80 for sound. However, the NeoGeo was a highly specialized piece of hardware and emulating it at full speed with sound is probably beyond even a PSP.
Even if someone could make a playable emu, many of the later games are too big to fit in the GP2X's 64 MB of RAM.
Hey, I'd love to be proven wrong.

specialized processors aren't a problem, the NeoGeo MVS and the NeoGeo CD use idential hardware (except for the stoarge media obviously) and look how well the NeoGeoCD is emulated on the PSP. The problem is the very large games that won't fit in 64bm of ram.

It's possible to get a NeoGeo emulator on the system but the problem is even with the 64mb of RAM only a few games will run.

must the whole game in the ram memory?
dynamic loading anyone?

Emulating the neogeo might be possible. the real problem is memory
Most of the memory is use by graphics. But those graphics are not directly usable, so it must be converted before used.... In the ideal case, we load all the graphic's roms, then convert it to ram in a usable format. With "only" 64MB of ram, we need do do it on the fly, and it'll be slower.
But the project is chalenging

What do you want?
Something like Metal Slug, one level at the time?

Humm, it's not that simple (at least for MVS).Jarska333 posted on Oct 14 2005 at 12:17 PM said:
But, mslug1 is not that big, and 64MB should be sufficient

Doesn't the xbox have 64mb of ram? There is a neogeo emu for it.
Or am I talking madness?

It also has HD for swap.

sorry i got the answer
For those of you who read Spanish (I will translate if anyone wants), on GP32 Spain, there was an "official" list from GamePark of the games that would run on the GP2X, and the list wasn't that short, course not that long either. If my memory serves me well, the "big hits" that could be played are Metal Slug 1 and 2. And KOF up to 97. Since KOF are my favorites, and seeing that they really couldn't be played, I really didn't pay too much attention to the rest of the post. However, if anyone would like more info on the games, I'd be more than happy to go back to GP32 Spain and look it up. Just give me a HA-LA, H.G.

What do you want?
Finite number of write-cycles on flash-memory.
well maybe there's hope when/if external hdd come into play.
btw, i wouldn't mind having a few 64mb sd cards just for virtual memory use...although write cycles shouldn't be that bad!
hmmm, wonder if you can hook up multiple sd cards? nah

Well, you know, those smaller SD's are rather cheap today... I wonder how much "swap" would actually be needed? And how fast it would actually get eaten?
I don't suppose there are SD-memory-chips or something? For PDA use or something, to be used as additional memory with heavy applications...

Well it depends how many writes the cards have in them, I always hear flash memory can stand 1,000-10,000 writes. If you play a game like Mark of the Wolves or a larger KOF game and it has to write for every match you could burn through them pretty quickly.
