Load boot.elf from Chain Loader. Insert any Wii Game and press reset. Enjoy your region free gaming. As of beta 5, Gecko OS works correctly with the [[Homebrew Channel]].
GeckoOS has the latest version of the Region Free app, which works with the [[Homebrew Channel]]. The latest version has increased compatibility with more games supported and issues running US games on PAL consoles fixed.
Note that while GeckoOS will enable the US Rock Band to load on a non-US console the guitars and drum set will not work (no controller ID lights lit). To load Rock Band try [[Menu Loader]] instead.
