I just bought one of these: http://www.modchip.ca/store/product.php?productid=16755&cat=313&page=1 I setup the kernel from their website: http://www.r4isdhc.com/download_silver_new/ When I pop the card in either my DS or my 3DS, it does detect the card and I can launch it from the DS menu. After that however, it gets stuck at a loading screen with a picture of a smiling folder. When I shut the DS off, and put the card back into my PC, it says the card needs to be formatted before it can be used. Very frustrating, any help would be great. I have some experience with these cards, I have setup a few in the past.
