Have you been sitting on the sidelines while all the cool people stick Linux distros and Snes9x on their "Twilight Hack" Wiis? Seems like there aren't any more excuses to keep out of the game now that you can do the hack with a regular SD card in the Wii's regular SD card slot -- no more GameCube memory adapters required. No fancy boot sector surgery is required either, you just drop a .elf file onto your memory card and you're ready to go. Check out the video after the break if you still need more convincing.
Update: Now with actual video goodness after the break.
