Greetings, I currently have a modded GameCube with the Cobra 1.2 BIOS. Unfortunately I'm having numerous problems with DREs. And I heard that changing the BIOS could help with that. Anyways, I got a torrent with all the available BIOS systems for the GameCube, I also got the new Cobra 2.1 BIOS. But I have a couple of questions concerning the matter. 1- Is there a way to install new BIOS without any extra hardware? 2- If I switch to another BIOS and I want to go back to my current BIOS (I have the files for Cobra 1.2), how would it be done? 3- What is the best BIOS system for the GameCube? Thanks in advance.
