Y'know after trying ModMii to update my Wii's hacking setup, I get it, but I honestly don't like it as much as doing things manually. Maybe if it had a more proper GUI (i.e. a gui not made out of an installer program retrofitted into a questionare about your console) I'd like it more, but eh.
Solid, but not something I'd use often probably. Good for beginners though tbh.
