The upcoming version plays most PSX games flawlessly. I'm currently using the beta and playing Tekken 3/Wipeout 2097/Metal Gear Solid. Compatiblity list, music, framerate and controls are absolutely astounding. The amount of work elemental has put into this emulator really is monumental.

Its the best looking PSX emulator with a myriad of features on any platform that I'm aware of. The new version will be launched as soon as he completes the built in help as far as I know.
