How to Upgrade Your Wii's Internal Memory
Adding memory to your Nintendo Wii will make you feel like a star. (Wii image by Lidka from

Part of the appeal of the Nintendo Wii is the vast array of games available to download via the Virtual Console and Wii Ware channels, as well as the ever-expanding line of channels themselves. However, downloading games like "Super Mario Bros. 2" and "World of Goo" eats up quite a bit of the system's meagre memory. There is an easy fix that will allow you to upgrade the memory for a few extra bucks without needing to pry open the system.

  1. 1

    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.

  2. 2

    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.

  3. 3

    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.

  4. 4

    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.

Tips and warnings

  • Games can be moved from the memory card to the Wii and vice versa as long as enough memory blocks remain free.
  • Not all save files can be moved to the memory card. If the "Move" or "Copy" options aren't highlighted, you must erase them to free up space.
  • If you accidentally erase a game, you can re-download it for free. However, you can only download it to the original system where it was purchased.
  • You must have enough blocks open on the system to play games from the memory card. For example, clicking on "River City Ransom" under "Data Management">"Channels" reveals that it takes up 22 blocks of memory. As such, you must have at least 22 blocks free on the Wii to play the game.
