PSX4ALL for Dingoo is a port of handheld PlayStation emulator PSX4ALL to Linux for the Dingoo A320 (Dingux) by Ulrich Hecht.
It features MIPS to MIPS recompiling CPU emulation, and performance is acceptable, ranging from some 16-20 FPS in Gran Turismo to about 60 FPS in Tetris Plus (with some tweaks).
