Zodttd posted an update to his progress of his Playstation emulator for the GP2X:
I just figured out what caused A LOT of games not to run at all, or crash mid-game. I also converted about 90% of the interpreter (psx cpu emulation) to ARM assembly. Everything it working smoothly. So an update is seems on it's way, but Unai and I will have to take a break at some point to release it.
So the next update will have a more (but how much Im not sure) speed and a lot more compatibility.
Will keep everyone posted. Thanks.
Playstation Emulation on the GP2X could be the killer release to push it ahead of the PSP as the Handheld Homebrew King
