Matsu PSX Emulator Lite

Matsu PSX Emulator Lite is a PlayStation (One) emulator for Android that lets you enjoy a good part of the catalog from the first Sony console right from the comfort of your smartphone. The only problem? The emulator only accepts game images in .iso and .img format.

The emulator lets you either connect a controller to your Android or use customizable touch controls. Of course, the first option is more comfortable, but it sort of defeats the whole purpose of having a PlayStation emulator on your Android (as it's portable).

Matsu PSX Emulator Lite is a decent PSOne emulator that still has a good bit of room for improvement in terms of compatibility. On the bright side, though, it can find .bios automatically on your device.
