Ps2 Games are somethings released for PPSSPP and that is why there are confusions, but you can know this from the fact there is FIFA 14 and that is not available for PPSSPP, rather mods of PES are regarded as FIFA by another website. I also want to make it clear that PPSSPP is not a Playstation 2 emulator for Android, some people don’t know this and list thee, emulator, as being capable of playing PS2 games. There are many ps2 games that can be played on android with emulators such as popular God of War, Assassin Creed, e.t.c.
