Its my understanding to stay away from 3d titles so obviously everything i'm testing is 2d. No matter what I do, some games have corruption with frameskip on. Its likely an odd quirk in my machine.
I'd say you should try 3D games too. I've tested some games with pretty good results.
Resident Evil 1 Director's Cut works surprisingly well.
Pandemonium is playable.
Vagrant Story is playable too.
Final Fantasy IX is a bit slow but that's not a big problem for this kind of games. I guess FF VII and VIII will work faster.
Alien Trilogy works really well.
I wanted to play Herc's Adventure but the sound is all messed up, I get background music and full sound during cutscenes, but all sounds disapear or play randomly when actually playing.
FF VII runs great
Parasite Eve 2 seems to runs great too, need to turn on a fix in the settings
Alone in the Dark - The New Nightmare and Fear Effect 2 crash
Disney's Tarzan runs at half speed
Dino Crisis 2 freezed in the first cutscene
