Okay, so my friend has a modded Wii with a Wiikey and has the Homebrew Channel installed for it already. I would like him to put the must-have applications for it. The thing is, do I really need Starfall? What other applications besides emulators and DVDX should I put on the Wii? He hasn't updated to 4.0 yet, but what tutorial should I direct him to to make sure that everything works when he updates to 4.0 and nothing broken?
