I'm confused about how this whole memory card thing works. I don't have a file in my User\GC folder that's a .raw/.gci or whatever it is. I try to open the Memory Card manager to create one, or whatever, but there's nothing there to convert or whatever it needs to do. I open Animal Crossing, and it says the Memory Card in slot A needs to be formatted...so I press Start. Nothing happens, I guess bc there's no memory card in slot a. What do I do? How do I get a virtual memory card or whatever needs to be there? I don't get it and I'm getting really frustrated!
