I have home brew channel installed, and have been using that various apps/games on it perfectly. Now I want to set up the GC backup Launcher. I have wii system menu 3.3U, and according the the HBC I have IOS 36 v 12.18. According the the readme, I need IOS249 with backup support. I currently have neither of these things, which brings me onto my questions: How do I get my wii to IOS249? How do I set up backup support?
