In preparation for Freehax, I was going to go on to the eShop on my SysNAND and download all of the free titles, however I forgot that I had never set up my NNID in my SysNAND. If I enter it now, will it have any adverse effect on my EmuNAND eShop access? If so, is it safe to create a new NNID, and use a different NNID on each NAND?
