I've added some game channel forwarders to the Wii menu because they look awesome, but only from my own region (NTSC). I want to add some channels from Japanese games, and I'm not sure if doing that will kill my Wii or not. On a related note, I have both Bootmii and Preloader installed on my Wii, and I made a backup of my NAND or whatever it's called. So if I do break my Wii doing something stupid, will I be able to undo it? I'd like to know those two things before adding themes and foreign channels since those seem like 2 things that could easily brick my Wii.
