I deleted mine a while back, if your using a windows based system follow this quick 4 minute video, I always do it this way, then use GUI Format to fat32 my card
at times, i also think of getting rid of mine, the idea of having no emuNAND partition kind of makes me thing that the mSD will be cleaner.
and maybe loading times would slightly improve etc.
plus , the swapping of emuNAND into sysNAND makes sysNAND work just like emuNAND when you have the option to choose 'boot into updated sysNAND" from Aurei, yeah?
one note : i have done the swapping with my og3dsxl,but i have not yet deleted the emuNAND partition.
i will give that a try now, and i shall see what happens then, if my mSD content does not get wiped, i might go ahead and remove emuNAND from my n3dsxl mSD!
(and also the CMD option is abit too long, i will use Easus Partition Master program.)
i will report back.
