How to Put Codes on Your SD Card Into the Gecko OS

Installing homebrew software on a Nintendo Wii can allow you to run homemade applications that provide additional functionality. Gecko OS is a homebrew program that allows you to apply a set of cheat codes in a GCT format to a game running on your Wii. You can download and edit the codes on your PC and then transfer them to your Wii via an SD card.
