Alrighty, so here's the lowdown on the SD Card support:
Dolphin will automatically create a 128MB, FAT32 formatted sd card image when a game tries to access the sd card, and dolphin does not find a file called "sd.raw" in the main dolphin directory.
From there on, you can use sd card features in games and homebrew with no problem, with some exceptions (of course...), which I'll state later.
OK, so in order to edit the memcard image, just mount it as a vfat disk if you're on *nix, or use a program such as winimage or gizmo to mount the sd card file in windows. Easy enough.
The other big question is how to get your current sd card into a format dolphin can use. This is easy too...on linux at least. Just use dd to create an image of the card, name it "sd.raw", and put it in the correct location. In windows, you will have to have dolphin create an image (or create a FAT16/32 image in any manner you want), then open it in one of the aforementioned programs, and copy the files you want from your real sd card into the image that way.
OK, so now for the exceptions I noted earlier: if the software running on dolphin tries to use any key other than the public SD Card key to securely transfer data to/from the card, IT WILL NOT WORK. This may or may not be fixed in the future.
