With GameCube/Wii SD Media Launcher, you can run all your home brew Cube software on an unmodified GameCube, or on a Nintendo Wii in GameCube Mode. All you need to do is download the program of your choice from one of the many web pages dedicated to amateur programming on the Cube. Drag and drop it onto your SD card or burn to mini disc then plug it into your Wii or GameCube. Launch the application CD on your console and the home brew program is run from there. Easy! I have 2 of these and they work great. Get them from codejunkies. It's best to run games you burn to Mini DVDs as they work perfect. There's a maximum size of 2gb with sd cards so only 1 game can be placed on the sd card. The compatabillty is a lot lower too running from sd card. I have 40 of the best GameCube games burned to disc and they all play perfectly.
