I thought they were the same, however, after copying all my games and saves to my new TT, I now find they do not work, and the TT erases them the first time I play a game on it, but it overwrites the save file, with the exact same file. Ie zelda.sav becomes zelda.sav Anyone come across this? Or know of a solution?
Fixed it myself, if anyone ever has this problem its that R4 saves are .SAV and TTs are .sav Sorry for the triple post.
