Ok... I am finding your question slightly hard to understand. BIOS's are only helpful if you have a modchip. If you do, then Cobra 1.6 works, because it comes with a built in ripping program that goes on your computer. If you have no modchip, can't help you there.
whats the update for and is the program help my playing a bit like an original game that doesnt hang or what? what mindvd u are using ? and how to i do the updating to my GC?
Okay... First tell me if you have a modchip at all. That's the only way you can 'update' it. I generally use RITEKG04 Data discs, but sony works.
