PPSSPP is a PSP emulator for Android and other platforms. It is being developed at a rapid speed and compatibility is increasing quickly, but there are many games it doesn’t run yet.
Please go to http://www.ppsspp.org for more information.
No games are included with this download, you will have to dump your own PSP games and turn them into .ISO or .CSO files, or simply play free homebrew games, which are available online.

IMPORTANT: Please do not give bad reviews due to low compatibility. It takes time.
