I really can't imagine how it happened... I was playing Pokemon, and I plugged in my SD card to the computer to edit something in Pokesav. I did it, and everything was fine, but I noticed I misspelled the name of a Pokemon, so I turned off the game, plugged in the SD card, fixed the problem, and then put it in the R4DS. That's when my problems started happening. The R4DS was stuck on the "Loading..." screen! I tried taking out the SD card and putting it in several times and nothing happened... Tried removing the R4 and blowing some air into the DS slot, and still... and finally, I tried a different SD card, and it worked just fine. :/ So I'm guessing that my SD card is done for? I try plugging it in to the computer, but it doesn't even read it... which really sucks, because this was my good SD card.... all my good ROMS that I played daily and save files where in there... Can someone help me out please?
