Hello! I just got the R4i cartrige for the DSi from http://gocybershopping.ca in the mail today and have been having problems with it. I formatted the mini SD that came with it to FAT using Windows Explorer, then I went to the R4i card's website which is http://r4ultra.com and got the latest update and followed all the steps on the guide at the site. After that, I just put it in the DSi and it shows up as "Danny Phantom" for some odd reason(...) and when I hit it, I just get a "Loading..." screen. Any help would be greatly appreciated!
