It's kinda like a catch 22. Only a few games work on stock settings but since you can only touch one button at a time because of the screen you can't play any of the marios. Some of the more intensive games like chrono trigger and the donkey kong countries only work if you enable "c-core" in the settings which slows down gameplay dramatically. I use the emu to play monopoly because it plays better than the droid version. I have zelda and the final fantasies in there just to show off but the game play is too slow to really want to keep playing. I start then get so frustrated that I reload on my pc emu just so I can finish it.
