Well it has been a very long time since I have even messed with my son's GC and I used to got to tehskeens and mod that cube but sadly they are not around any longer. The last time I flashed the viper on my son's GC I used a disc with cobra v1.6 on it. Is there a downoad for the cobra 2.1 bios update that I can burn to a disc or do I have to go about it a differnt way now? If it has to be done differently could someone please link me to it. I downloaded the cobra 2.1 bios update but it was all files and did not know how to flash it to the chip on the GC. Thank you for any help with this matter.
