Well if you do hack it, you'll be able to...Play Homebrew games, and emulators. You can play backups on it(downloaded games, burned to DVD) both Gamecube and Wii games, and you can even play DVDs on it!
If you have a 3.2 version, and have a copy of Zelda: The twilight princess Then you're eligible to hack your wii
Well I'm waiting on a few maps, so I can script, but so far I've got the place where you encounter entei completed. If you want to see the map that is...I also made another town, and some sea routes. I have a lot to do though
