homebrew is the software written by people to run on your wii!
2. WTF is Homebrew? Is it a program, a site, part of soft modding, what?!?
it wont matter what region the game is, you just need to be careful that if you were to accept an update from a disc that was from a different region , then you would end up with a possible brick. All backup launchers and USB launchers will prevent updates, as will Preloader.
4. Once I've soft-modded this thing, I can just dl or back up any game and it will play? Will it matter what region the game came from originally, i.e. PAL or NTSC??
