Taking a dip into the homebrew waters just got a little bit easier.
A new exploit for the Wii has been uncovered which does not require the use of any Wii game discs, unlike other current methods. The exploit, titled LetterBomb, was developed by hackers known as blasty and tueidj. It uses the Wii Message Board as a conduit to bypass the Wii's security and load the HackMii Installer, which loads the Homebrew Channel onto the Wii System Menu.
The exploit is mostly automated, but requires a few pieces of information, such as your Wii's physical networking (or MAC) address. A website has been set up at http://please.hackmii.com which can prepare a zip file, which you place directly onto an SD card and then into your Wii.
The hack is meant to break through Wii system firmware 4.3, which is the latest update from Nintendo, released last year, and one that blocked the previous game-free exploit, BannerBomb. Coupled with Gecko OS, the exploit comes just in time for those with American Wiis interested in playing PAL import copies of Xenoblade Chronicles. Keep in mind that installing homebrew will void your warranty.
