Instructions
Click the Wii icon in the lower left corner of the Wii's main menu. This brings up the system options for the console.
Choose Data Management from the list of options. Data Management contains all saved files and system configurations.
Select Wii Data to access your saved games. The games will appear listed by the name of the game and also show the file size of each.
Insert an SD or SDHC memory card into the card slot on the Wii Console. The card slot appears near the GameCube controller slots on the back of the unit.
Click the saved game files to bring up the file save menu.
Select Save to SD card from the list of options.
Repeat this process for each file you wish to copy.
Eject the SD card and place it in the second Wii console. You may then reverse the process to copy the files to the Wii memory on the second unit, or simply play the game.
