Harvest moon and raiden project give 10+fps (faster than quake

). More complex games (like Crash Bandacoot2) give 3-4. Some games get up to 20fps though.
Note:You do not need a rom to test this emu. Simply go to load iso, then click cancle, and it should open the psx and show both bios screens, just as a real psx would if you started it with a music cd (I believe)
