So, I got my G6 Real DS card a day or two ago. Already I'm having problems with it. To be specific, certain homebrew things won't let me load or save, and others won't work. I found out why. They can't reference other files. To give you specifics, I've tried playing Crawl DS, and it won't save (can still play it, though). The error it gives is "No FAT filesystem detected". This, I have deducted, means that these things haven't been working right because it can't detect any FAT system. I've tried formatting the card several times, and even in FAT32 (I assumed the thing was in FAT16 by default), and I still get that error message, and games still can't reference other files. Can anyone help me here?
