I wanted to continue playin my days of ruin file so i turned on my ds and went to days of ruin on my micro sd thats on my m3. So after i went to days of ruin, my game froze. I tried turning it bak on and i get the message tf/sd card error. I tried takin the card out and puttin it bak into the m3 and stuff like that and kept gettin the same error. I then decided to put the card into my computer to see if i can fix it there. I put it in and it says i need to format the disk before it can be read. I don't want to lose all of my data. How do i fix this?
kenio8185, Copy all your ROMs to your PC HDD first. Reformat the card and download/install the most recent firmware for M3 here.
