I applied a friend's save taken from his cart onto mine, and it didn't turn up corrupted. You have to change the string of numbers/letters in the beginning of the filename of the save to match that of a save from your game, and it'll recognize it as a save your game has made.Won't work. Datel's servers will try to decrypt khalaan's save file using your game's unique decryption key, not his. Try to load his Y version onto your game, and it'll say it's corrupted.
