Ok I recently put advanced wars days of ruin on my sd card for my M3 DS real. Well all was fine, played a round or two of it, then saved and shut my ds off. Didnt think anything of it, cause i had something to do. So a few hours later i go to play my ds again, and it just sets at the loading screen of the M3 DS real. Wont boot at all. I tried it several times. So I was like wtf took the sd card out and put it in the card reader, and it wont open, it shows it at 0 bytes. NOthing on there, cant format it to get the space back it just says 0 in the space. This made me wonder, did the game fry my sd card? Or what? Is there anything i could possibly do to get the sd card working again? Lost all my saves which pissed me off, but thank god I had another 2 gig card for my phone that i robbed from peter to give to paul so i could play games lol. Any thoughts and ideas on this?
