Is there some tool to adjust the emuNAND region to fit a n3DS NAND image, or alternatively could it be done by resizing the partition in, say, EASEUS Partition Master to a specific size? Also, if the o3DS emuNAND image is still intact, would it still boot fine even with the unformatted region extended? I'm going to MAGFest in a couple days and planning to buy a n3DS there, and I'd like to save myself the time/headache of having to backup, reformat and restore yet again (already had to do that song and dance once when the 3DS stopped reading my SD cart...) especially at the event.
