I actually downloaded this in the hopes I would be able to play a couple of my favorite Nintendo 64 games on a tablet which are Perfect Dark and Pokemon Puzzle League and I would have to say this is 1 for 2. Perfect Dark runs flawlessly and at full speed however in the case of Pokemon Puzzle League it crashes immediately and does not even make it to the opening screen. Over all I would say this emulator is promising but the CPU core and perhaps graphics emuation desperately needs some work in order to improve compatibility.
