Hi,
I have a GP2X - F100 and i have played Amiga games with various results, if you put the clock speed up you can get some very playable games. Some games also run very slow.
It is still a great machine and is better for Mame, Snes and megadrive and 8-bit classic emulation in my opinion.
Quote! I have also a GP2X F100 console, many(most) amiga games run very well, others not.
