I want to save my gamecube games, but I cant because im a memory card short. I have an SD card, so will this work? http://cgi.ebay.com/SD-Memory-Card-Adapter...1QQcmdZViewItem I imagine it would, but I dont want to waste $10 if it doesnt. thanks!! EDIT: theres a 4mb memory card which comes with a controller I also need. it doesnt sound very big, how many saves can it hold?
