How to Hack Your Wii For Homebrew Apps and Games

Wii的漏洞就是需要讀入專用存檔, 讓Wii讀入一個檔案會重開機並自動執行你SD卡根目錄下的boot.elf程式。（或者是boot.dol。一般來說，wii的應用程式就是elf和dol這兩種尾碼）
boot.elf(dol)可以是任何程式。比如，你想裝wad的時候，將wadinstaller.elf改名為boot.elf，放入SD卡根目錄。

Homebrew(自製) Channel

Homebrew is unofficial software created for a platform by its users, without the involvement of the vendor.

The Homebrew Channel is a self-updating homebrew application loader, once installed, users can access the channel from the Wii System Menu just like any other Wii channel.
It can launch or install homebrew applications from an SD or SDHC card or via TCP/USB Gecko using Wiiload.
To install homebrew, you run an exploit first. The exploit crashes the Wii and runs unsigned code in the form of a .dol(.elf_ file on the root of your SD Card. If that unsigned code is the hackmii installer, you can then install the Homebrew Channel, DVDX, or BootMii.

What You Need

• A Wii running the latest Wii System Menu 4.2 (of course, Wii Homebrew is possible on older versions, but the installation process is slightly different, so for the sake of this how-to, I will assume you have the newest update).
• HackMii Installer v0.6 and Bannerbomb v2.
• An SD card (FAT32 formatted) and Wi-Fi connection.

How to Install Wii Homebrew

• Download Bannerbomb v2 and HackMii.
• Create a folder named “private” on the root level of your SD card if there isn’t one already.
• Unzip the Bannerbomb files to your SD card.
• Copy the HackMii installer file, “installer.elf,” to the root of your SD card and rename it to “boot.elf”.
• Now fire up your Wii and go to SD Card menu in the bottom left of the home/channel screen. Insert your SD card. It should pop up a dialog asking you to “Load boot.dol/elf?” to which you should say yes. This will install the Bannerbomb exploit which is what makes Homebrew possible.
• Bannerbomb will then run the “HackMii” installer which installs the Homebrew Channel. It can also optionally install DVDx (which lets you use apps that use the DVD drive: recommended) and BootMii (which protects against bricking). Once that is done, you will have a new Channel on your home screen called “The Homebrew Channel,” and the geeky fun can really begin!

Apps to Check Out

Here are some other apps to check out once you have Homebrew running:

• The Homebrew Browser: An app that lets you browse and install homebrew apps to your SD card straight from your Wii; without this, you have to remove the SD cards and copy apps onto it using your computer.
• Gecko OS: Lets you play Wii discs from other regions (DVDx required). Additionally, Gecko OS now includes “Ocarina” a homebrew cheat app, reminiscent of Action Replay or Game Genie.
• MPlayer CE: A media player for Wii (DVDx required) that includes playlists and DVD movie playback.
• Wii-Linux: No hardware hack would be complete without the obligatory Linux build!
