As of August 2019, the most common method is to use an Action Replay in conjunction with an SD card adapter inserted into the memory card slot, allowing the user to run homebrew from the SD card, or over Ethernet. Another method involves using a modchip to allow the GameCube to run homebrew from a MiniDVD-R via the disc drive. Another method uses a save game exploit which involves transferring modified game save files to a GameCube memory card that triggers arbitrary code execution when loaded by an official game, allowing custom software to be run from a memory card, SD card, or other media. As the Nintendo GameCube's case does not fit a full-size DVD-R, third party replacement cases are available.
