If you are trying to back up your save for Gen 3 Gamecube games there are a few things you will need. The main device I will be using in this tutorial is a hacked Wii with homebrew installed. Note: with this method you will be able to make an exact clone of your gamecube memory card which is extremely useful for emulators, and makes transferring to a new memory card a breeze.
6. Eject your SD card from your Wii and insert it into your computer. Then navigate to "MCBACKUP". Inside this folder will be your memory card file.
7. MAKE A BACKUP OF THIS FILE BEFORE USING OR EDITING IT WITH ANY SAVE EDITORS.
