all you have to do is open up the .tap file (from tap tap revolution) with a text editor and at the top you add #title "name of song" #artist "name of artist" #id "######" convert the mp3 song file to aac (not sure if this is needed, but my mp3 wouldnt work) you can use itunes to do this. name the aac file and the .tap file the same, but after the .tap files name add (difficulty) ex. All That Remains - Six.m4a All That Remains - Six (medium).tap now find your ttr.app in /var/mobile/Applications (its all numbers, just open them until you find one with a tap tap folder) import the song file to Documents/Tap Tap Revenge/Music (inside the app folder) import the tap file to Documents/Tap Tap Revenge/Taps shakes, one-player, and two-player are all compatible! note: when playing these .tap files, some notes will be off. it is still playable, but you will have to change every line of code to make it look better.
