I got my hands on a Nintendo GameCube Service Disc Version 1.0/03. However, when I put in in a GameCube (I've tried two different ones), I just get a black screen and no audio after the initial boot-up sequence. If I go into the system menu, the GameCube properly recgnoizes the disc. Do you guys know if there's anything special I need to do to play/view the disc? Do I need to hold down a button or perhaps have a special file on a memory card or something? Thanks.
