Okay, I have the latest version of Tap Tap Revenge 2 (I think it's 2.6) and OS 3.0. I downloaded Tap Maker earlier today and made a short test song. It came out with the .m4a and .tap files, so I SSH'ed into my iPod and found the Tap Tap.app directory. And now ... I have no idea where to put the files. Actually, now that I think about it, I'm not even sure that Tap Maker works with TTR2. I'm going to go download the original TTR and try it with that. Any thoughts?
