Things You'll Need
Instructions
Insert a blank memory card into Slot B on the front face of the Gamecube.
Locate a memory card that holds the game file you want to backup. You probably already use at least one memory card, since many Gamecube games cannot be played without one. Insert the memory card with saved game files into Slot A. Game files appear on the screen.
Find the the game file you want to copy. Highlight it with your controller. Press the A button on the controller.
Watch for the screen to ask whether you want to copy, move or delete. Highlight "Copy," and press the A button again.
Look for the screen that asks if you are certain that you want to copy the file to the second memory card. Highlight "Yes." Press the A button to complete your selection.
Wait for the copy function to complete. Remove the memory cards after the process is complete and before turning off the Gamecube. Removing memory cards during copying can damage the memory cards.
