I have a Viper Extreme with USB Adapter. Getting the gamecube to connect to my pc was a pain but I just needed the driver for it. So I finally connected with cobra backup an did a full backup thinking that would be the end of my troubles but it wasn't. It came out as just File. So I renamed it adding .iso but it wouldn't burn with dvd decrypter. I heard I needed to use nero burning rom but tried an alternative. That did burn but when I selected direct boot on the main menu it would just freeze. So I used Nero Express since I had a CD of it but when I selected direct boot it looked like it was about to but didn't. It game me this message: The disc could not be read. Please read the Nintendo GameCube Instruction Booklet for more information.
