I'm still running 4.1U. First, of all, is there a homebrew I can use to see information about what kind of hacking related stuff I have installed? (I'm pretty sure I have starfall, and I recall there being something that replaced all IOS files with cIOS files so I can read backup discs from the disc channel, although even when I left that was useless because everything had migrated to WBFS format drives.) Second of all, is there an easy way to bring myself up to speed? I see that gamecube games run via USB now and a couple other advances have been made, but what's happened in the last while that's worth knowing?
