There are many emulators for PSP, such as the Snes9xTYL and the PSP-GBA emulator. But it has been a long time since they had been updated for the last time. Did the creators stopped? I don't know, I just think that if someone can make a SNES [or a GBA] emu perfectly, the community will make him 'god'. If someone knows what's happening about these two emus, inform me please.
