Things You'll Need
Instructions
Navigate to the "Homebrew Applications" page on the Wii Brew website. Download the homebrew games, applications and emulators you would like by clicking on them. Extract the files if necessary. Check the emulator compatibility lists on their corresponding websites to see which games will play in the emulator.
Insert a SD or SDHC card into your computer and click on "My Computer." Right-click on the SD card and select "FAT32" as your file system. Keep the "Allocation Unit" size at 4,096 bytes. Check the "Quick Format" box and select "Start" to format and partition your SD card so it can be read by the Nintendo Wii.
Create a folder named "Apps" for homebrew applications, games, emulators and Wii system utilities. Place your files into the "Apps" folder. Some emulators also require a directory be placed on the root of the SD card which contains the emulator ROMS and game-saves folder. The emulators read the ROMS and saves from this root folder.
Insert the SD card into your Wii and turn it on. Navigate to the homebrew channel and load the channel by pressing "A" to start. Browse through the emulators, applications, system utilities and homebrew games. Press "A" to launch the different homebrew applications or games.
