NDeSmuME 0.4.0 (Open Source)
Heres a emu that runs games and is open source , it might be worth a shot at porting it just cause its possible and its not as crazy as it might seem , psp already has some fun just-cause-its-possible ports like the Jaguar emu. Maybe on a day when ZX-81 gets bored he might jump on it ;)
This emu worked suprisingly well on my p2 400mhz here are some screenshots I took: http://img124.imageshack.us/img124/2972/ds6nc.png
