FCEU-PSP is an attempt to port FCEUltra, a great Nintendo Entertainment System emulator, for PSP. This is the first project of a “newbie” in the PSP programming world, so there will be always something to be improved.

FCEU-PSP is opensource and you can help the author to make it better.

Changes:

Changed codebase from FCEUltra 0.98.12 to FCEUltra Mappers Modified (jun16-2006)
Mappers compatibility increased (thanks to the fceumm codebase update)
Mapper 163/164 bugfixed based on FCEUX sources (FF7 Remake is now playable)
Improved the menu rendering a little
