i would like to see someone port the ZSNES emulator to the GP32,that is by far the fastest,and best emu for windows,so it should be the best choice for the GP32 i would think!
The sources for ZSNES are in C though, well either C or C++ can't remember. I wanted to say zsnes would be fast on gp32, but everyone told me snes9x would be better at every aspect.
