Confirm your SD card is compatible for use with the Wii. Check the Wii Brew SD/SDHC compatibility list.
Navigate to the Wii Brew website, and choose which method you would like to use to install the Homebrew Channel to your Nintendo Wii. The Twilight Hack and Bannerbomb method require that you have a Wii System Menu 3.2 through 4.2, depending on the loader you use. The Indiana PWNS, Brawl Smash and Twilight Hack method require you have either the "Indiana Jones," "Super Smash Bros Brawl" or "Zelda: Twilight Princess" Wii game. Indiana PWNS and Brawl Smash loader can load the Homebrew Channel on any Wii System Menu version.
Navigate to the "Games" section on the Wii Brew website for a collection of Wii Homebrew games.
Click on the Homebrew game you are interested in to download it. You may need to unpack the file.
Copy the files for the loaders onto the root of the SD card.
Create a folder named "Apps," and place the loader application files in the folder. You may also need to place files on the root of the SD card, depending on the loader you are using.
Place the Homebrew games into the Apps folder.
Insert your SD card into your Wii, and depending on the loader you are using, either insert the "Indiana Jones," "Super Smash Bros Brawl" or "Twilight Princess" game and play to the certain point on the game level to trigger the hack to load Homebrew Channel.
