I never had a gamecube, so I am not sure exactly how this works. It won't let me save any gamecube games or roms onto my Wii directly. Do I need to buy a gamecube memory card? Or will a SDcard that the Wii takes work? It would be nice if I could buy a memory adapter that would work for both Wii games and GC games. If you have any suggestions please give me a name and/or link.
