This stuff has only been tested on an NTSC Wii with firmware version 4.3U installed. If you want to install it on anything else, I can NOT stress enough how important it is that you have brick protection installed on your system.
My first foray into custom Wii channels, the Wozbrew Channel is functionally identical to the Homebrew Channel, it simply has a Scott the Woz theme to it.
