Things You'll Need
Instructions
Insert your Wii SD card into your USB adapter if your computer does not have an SD card slot. An SD card is a flat, rectangular, white piece of plastic that stores excess data from your device. If your computer has an SD card slot, it will be clearly marked with the word "SD" beside it. Click "Show Files" when prompted.
Insert your homebrew disc into your computer. Click "Show Files" when prompted.
Click to highlight the homebrew games you wish to add to your Wii. Drag these highlight files into the window showing the SD card files.
Remove the SD card from the slot or its adapter.
Open the Wii SD card door, located on the front of the console. Insert the SD card into the slot until it clicks, and then close the door. This automatically loads the games into your Wii, allowing you to access them and play them through the Wii menu.
