Does anyone know where I can find a no cd/dvd patch for Guitar Hero 3 for mac? I would much rather just leave the disc in its case so it doesn't get scratched and could still play the game. Also, does anyone know if there are any more songs you can download yet? I would have expected there to be some since its been out for a couple months. I'm getting kinda tired of always playing the same songs, it would be nice if you could add your own or download some more. Thanks.
