LetterBomb is a safe way to enable homebrew on a Wii without hardware modification. LetterBomb is achieved by use of the Wii Message Board which executes a homebrew application from an external SD card. Examples of such homebrew .elf or .dol files can be found on the Homebrew applications page. LetterBomb was created by Team Twiizers. This exploit only works with any region of System Menu 4.3.
This exploit is a System Menu exploit, meaning it works without needing a game, similar to the now defunct Bannerbomb.
Usage & Installation
For detailed instructions on using this method to set up Homebrew from start to finish, see Letterbomb
- SD or SDHC formatted as FAT16 or FAT32.
- System Menu 4.3 (anything lower will not work).
- Your Wii’s WiFi MAC Address (available from your Wii's system settings). This is needed because the Wii will only accept messages addressed to its specific MAC address.
- A way to copy the files from your PC to the SD card (card reader, printer, etc.)
- Some homebrew software to load. Although this isn't necessary, it's highly recommended. The exploit will attempt to load "boot.elf" (or "boot.dol" if it can't be found) from the SD card root directory.
- Note! If your Wii has any of these accessories, the Letterbomb might not appear in your messages: attachable Motion Plus, GameCube controller, GameCube memory card. Please remove these before attempting to find the message. Those with controllers that have the Motion Plus as part of the hardware of the remote, the LetterBomb will appear as normal.
- On Computer: If there is a folder titled "private" on your SD card, rename it to "privateold"
- On Computer: Copy the "private" directory from the LetterBomb download to the root of your SD card.
- On Computer: Take your homebrew (preferably Hackmii Installer) and put it in the ROOT of your SD card as "boot.elf" Note that you can download the Hackmii Installer directly from the download link provided above.
- Wii: Put your SD card in your Wii and turn it on.
- Wii: Go into the Wii Message Board and navigate to "Today", "Yesterday" or "Two days ago".
- Wii: Click on the appropriate envelope, sit back and prepare for the hacking glory.
