The PPSSPP multi-platform emulator Android, Windows, iOS, Mac OSX, Blackberry, Maemo, Harmattan, Symbian, Pandora, Linux updates to version V1.4.
PPSSPP is the first PSP emulator for Android, and other mobile platforms, which runs much faster than any other PSP emulator on Windows, Linux and MacOSX.
PPSSPP can run your PSP games in full HD resolution, save and restore game states at any time and allows you to continue where you have stopped the game by transferring backups of your PSP in real time. It also allows you to create HD textures using anisotropic filtering and texture scaling that otherwise would seem too blurry as they were designed for the small screen of the original PSP.
