P.S Sorry for my bad english
We have a better method. After you've flashed your emuNAND to your sysNAND, just backup your SD card. From there, download
emuNAND9 and use the option to Format without emuNAND.
It will properly reformat your SD for the 3DS and remove the emuNAND. Then just restore everything back to your SD card.
Another step to clean up some space, is to delete the no longer needed folder in the "Nintendo 3DS." Folder. There should be two in there, one smaller one (which should be your old sysNAND,) and one larger one, (which will be your old emuNAND, now current sysNAND.) Just delete the smaller one.
