PCSP is a PSP emulator written in C++ for Windows. PCSP was never able to emulate any commercial games, however it could run some homebrew, ultimately development never got far enough for PCSP to emulate enough of the PSP to run any games.
Development of the emulator has also sadly ceased. There was an attempt to rewrite the emulator under a new project PSPE4All but that project ultimately never got off the ground, and no release was ever made.
Don’t expect to be able to run any commercial game with this emulator, for that purpose we recommend an emulator such as PPSSPP instead.
