I have an older Wii running system menu 4.3u. I've successfully run Letterbomb and have the Wii Homebrew channel and bootmii installed (IOS method). I want to play Wii games off either a backed up DVD (preferable initially) or USB HD (maybe down the road). I'm sorry, I've read guide after guide and can't quite figure it all out. What do I do to complete the process that will allow me to do this?
