Ok I just installed the Homebrew Channel and Bootmii and made a backup of nand and keys, I tried running my US GC discs and they weren't readable so I take it that I still have stuff to install? something like Gecko OS? (is there a best choice?)
Edit: Just did some searching around, StartPatch seems nice because it runs from the disc channel, so should I install IOS236 and StartPatch (or are there better choices?)
