Sorry but those emus are for psp and are optimized for it. Porting to an arm architecture is not trivial. A lot of code should be rewritted. The cps2emu source code that i take was from a gp2x port, gp2x has similar architecture and only a little bit of code was rewritted to be able to run on the n900.

Anyways, i did a gngeo port with some optimitzations for the n900, but i didnt publish it yet because lack of time. Perhaps someone is interested on it.

Regards.
