PSX emulator for Android phones
This project is based on sources published by original psx4droid developer (or someone else – I don't care as it is all GPLed anyway), who in turn used code of PCSX-ReARMed, forked from PCSX-Reloaded, based on PCSX-df and original PCSX...
This project is abandoned in favor of libretro PCSX-ReARMed variant: https://github.com/libretro/pcsx_rearmed. Current sources already depend on recent version of platform anyway.
Love that its free
