Playstation (PSX) BiosPlaystation Emulators, such as FPse and PSX4Droid, require you to have a Playstation BIOS to operate. You can think of Playstation BIOS as a set of instructions to jump start the Playstation Emulator. Without it, you will not be able to play the games or ROMs in our case.
What you need to do is download the Playstation BIOS, unZIP it, and then place in the same folder as the roms. Afterwards, load it into the emulator just like you would open a ROM. When completed, you will be able to select a ROM and play.
*You only need 1 of the 3 Playstation BIOS Files listed, the one that works best with FPse Android Emulator is SCPH1001. Pick SCHPH1001 unless you know which one you need.
