Things You'll Need
Instructions
Make sure your Wii is modified with a Wiikey. Without one, you will not be able to rip games for it. You can have Wiikey installed for you, or install it yourself.
Plug in the Gecko adapter and SD card into your Wii's Gamecube memory card slot. It will then ask you to load a disk.
Load whatever Wii or Gamecube game you want to rip. It will save the files on the SD card, but the card is too small to fit the whole game. Once it has dumped all the information it can hold, remove the SD card and put the files on your computer. Erase the card and put it back in the memory card slot and continue copying the game's information. For a Wii game, you will have to do this three times.
Combine the files into one file--as once you have the entire game on your computer, it will usually be in three separate pieces.
Burn the game file onto a 4.7 GB DVD disk and play it on your Wii. Due to the Wii's protection software, only modified Wiis can play ripped Wii games.
