"Team Twiizers" have just released a hacked save file for The Legend of Zelda: Twilight Princess that allows unsigned code to run. It requires nothing more than an SD card and a copy of Twilight Princess -- no hardware modding needed. Check out the video above, which features not only a demonstration of the hack at work, but also some neat chiptunes from Thomas Detert.
This is just a proof of concept at the moment, but at the end of the video, the group promises an ELF loader, which would allow the Wii to run Linux. This isn't the first time someone has hacked the Wii, but it is the first time the tools have been made available. We look forward to the inevitable rush of neat Wii homebrew applications, if this hack is actually developed to a useful stage.
