A free program for Android, by EmuBox JSC.

EmuBox is a revolutionary all-in-one console emulator for Android that allows users to play their old game ROMs on their Android phones. It is the first multi-emulator with Material Design, allowing users to scan their own game files and play them for free. It features a PSX (PS1) emulator, Nin emulator, and the ability to save and load game states up to 20 save slots per ROM. 

Additionally, users have the ability to take screenshots of their games, fast forward, and play with external controllers either plugged in or with a bluetooth gamepad. However, it is important to note that EmuBox does not include any game ROMs, and is intended for users to play their private ROM backups only.
