gc-forever - Gamecube/Wii Forums

Hi I recently dug up an old friends icedcube with Viper GC chip I'm assuming because it has cobra version 1.2. It plays one of his voewtiful Joe burnt CDs as well as an original Mario kart but the iso files I make using imgburn don't read. I'd try to fix this myself but when I start the cube it only stays on the cobra page for a second before going full retail GameCube mode. Is there a way to access the bios of cobra 1.2? I'm a complete new to this and visually impaired so any help would make an early Christmas .

which viper gc is it and can you post images or a vid thanks.
also when you say isos you make what exactly do you mean.
