The awaited SNES emulator for PSP has been released. This one is confirmed to work and it’s not a fake. It runs a bit slow, but it has SOUND and please remember this is for v1.0 firmware only. It will not work on your v1.50+ systems. It is running at 10 ? 40 fps depending on the game. It also is less than half the screen (the top left corner). Also make sure that the folder is called snes9x. As all PSP homebrewn programs, please keep in mind it does need a japanese v1 bios to work.
