It's only been a short while since we saw the first successful attempts at Wii homebrew, but things now look to have busted wide open, with hacks seemingly turning up left and right these days. Most notably, the folks from the GameCube Linux project have recently let loose a proof of concept Linux "mini-distro" that makes use of the now infamous Twilight Princess hack to turn the Wii into a tiny (and so far not very useful) Linux box. If that's a bit too much you, however, you may be interested in some of the tamer homebrew fare that recently made its debut, including an MP3 player and, you guessed it, an SNES emulator. In related news, Nintendo also just pushed out an official updated to the Wii OS (version 3.2), but contrary to what the timing would suggest, it apparently doesn't do anything to block you from getting your homebrew fix.
