Handy2xHandy2x was a port of HandySDL (SDLEmu), an Atari Lynx emulator, to the GP2x hardware.
It is working, but lacks sound and is not fullspeed.
There is a better Port, GP2XHandy, made by TuskenRaider. I really recomment you to use his emulator.
If you still want my port, you can get it here: handy2x02.zip
EFCSEFCS is currently emulating Chip8 - some really old stuff ;)
I still plan to emulate more systems, but I don't find time to work on the emulator.
You can get the current version here: efcs01.zip
