As of yesterday, my M3DSReal was working just fine. But today, the M3 loader doesn't come up and the ds bios just continues everytime I turn it on. I checked the microSD card and all the the files were intact, so it is apparently not corrupted. I made a backup just in case (the card is a Sandisk 4gb). Any suggestions on what I should do? Latest firmware was installed and working as of yesterday.
