I'm excited to see this one come to full fruition. WiiMU from homebrew devs SquidMan and crediar is an ambitious project that aims to completely replace the Wii's System Menu. Now on version 3, the program now has several new features and bug fixes. The devs note that: There are some slight problems with 0.1a3. First, on the channel list, you may get two listings of a channel. Choose the first one. Second, the elf file is named WiiMU.elf. You must rename it to boot.elf for it to work. These issues have already been brought to attention and will be fixed in a4

Remember to go through the readme before installing the program
