Okay folks, now that I've been playing with emuNAND and also been reading some threads, here's what's going on:
Your mSDs & SDs aren't bad. They're just not formatted properly.
The 3DS uses FAT32 MBR formats. Some flashcarts have special formats like Gateway for emuNAND and Sky3DS for Diskwriter.
Your brand-new-super-fast mSD may be out-of-box, but that's doesn't mean it'll work.
For any SD to work in the 3DS it -HAS- to be MBR - FAT32 - PRIMARY PARTITION.
The problem? Most mSD's...
