So nice. Got a pretty good deal but it doesn’t have a stylus.
Edit: Ugh…I’m having SD card slot issues. getting a “the device inserted in the sd card slot cannot be used” message. The card is formatted as FAT32 correctly and works on other devices. Hopefully the slot just needs a clean…. the manual is of no help.

EDIT: ok good news and bad news. I found a SD card that gets detected as it should. Bad news: It’s 16MB. Yes. MB.
Well, at least I know my DSi hardware is ok, but now to find a card that works. From what I can tell, the only difference between them looks to be physical. The smaller card (black) is flat on the back where the contacts are, but the larger cards (blue) that don’t work have larger divits between the plastic and the contacts. I tried taking a picture but it might not be so clear. So I’m thinking that the card reader in the DSi might not be grabbing the card as closely as it should be…The small one is so old, its when they were called “Multimedia Cards”.
