Not PSP, but PPSSPP. It is a PSP emulator. For a medium quality computer, playing with PS2 emulator is not that smooth. But PPSSPP is good enough to play the PSP games. And there is an Android port for PPSSPP, but only if your phone is strong enough to run the game.

Thanks to the open source and PPSSPP developers.

Other emulators which I like are VBA-M (a fork of inactive VisualBoy Advance), PCSX-Reload, PCSX2, FCEUX, Snes9x, and DOSBox. But FCEUX, Snes9x, and DOSBox games are extremely antique.
