It's been a while since I've visited this site, and I need a little help. Thanksgiving Day sales at Walmart drove me to get a 3DS XL. I brought it home to find it's on Firmware 8.1.0-19U. I know this is a very good thing, but I have no idea how to *properly* go about accessing my system's true potential. If someone would help me I would be greatly appreciative! Thanks in advance!
