LetterBomb does game-free Wii hacking for System Menu 4.3
The myth of the unhackable Wii has long since been put to rest, but that hasn't stopped intrepid homebrew enthusiasts from coming up with new exploits. Case in point: LetterBomb. This particular Wii hack is a follow-up to BannerBomb, which was billed as a replacement for Twilight Hack -- all of which are capable of launching the homebrew channel sans hardware mods. BannerBomb stopped short at Menu 4.2, but LetterBomb is carrying the exploit banner, so to speak, for the next generation. Utilizing the console's Message Board, the hack requires an SD card, a Wii running System Menu 4.3, and a Wii MAC address. If you're looking to get your game-free Wii hack on, check out the source link for the full rundown.
