Do you have to use single layer discs to burn the backups? I ask because I keep making coasters and I only have dual layer available at the moment. The nest question this........if your modchip (in this case a wiikey) is installed incorrectly, will the wiikey setup disc work? I ask this because I am trying to verify that my chip is installed correctly, the setup disc works, but my backups do not seem to be. Any ideas? btw I am using verbatim dual layer and nero 6 to burn the game. I own the game in question, but I had to get the iso from other sources since I do not own the burner/s required for the backup.
