I haven't put on to many games, but for the most part, the ones I have put on, worked fine. The only game that is a real pain is Tetris Worlds (and honestly, I don't want to play it, I deleted it lol). Everything else works great. I have noticed the sound in a lot of the games is glitchy. My solution? Mute the sound and listen to my music, you don't notice any problems. The frame rate drops sometimes, but that even happened when you were playing some games on the original system. Great job who ever worked on this, I'm sure in time it will get better if you decide to continue working on it. This really makes the Touch worth the money, thanks a lot!
