Very good list, great work! I've never actually bothered to try so many games cause the few games I tried disappointed me so much. They were unplayable because of the high frameskip. I don't think MAME is the optimal arcade emulator solution for PSP. It would be better to port an emulator more optimized for speed than compatibility. In my opinium it's better to have an emulator that emulates only a few games at high speed than having MAME that run almost every arcade game but at very low speed.
