Instructions
Open the small door on the front of your Wii, located just below the reset button. Insert the flash memory card (label facing right) into the slot just below the red "sync" button.
Turn on the Wii. Click on the Wii logo in the lower left-hand corner. Select "Data Management." Choose "Save Data" to access game save files, or "Channels" to access downloaded Virtual Console and Wii Ware games.
Select "Channels" to move the memory-hogging Virtual Console and Wii Ware games to the memory card. Click on the icon of the game that you want to access and select "Move." Choose "Yes" when asked if you want to move it to the SD card. Hit the trigger button to exit to the main menu once the process is complete.
Click on the memory card next to the Wii logo in the lower left of the screen and select the game you want to access. Choose "Start" to play the game from the memory card.
