First of all, sorry if this has been answered before, I searched but couldn't find a direct answer. I currently have a 4.5 3DS XL with GW running emunand 8.1.0-19U I updated to this a while ago, when smashbros was released and I did that by formatting my current emunand (after backing up etc), I was a little disappointed that the new emunand was totally fresh, so all my play stats and settings were lost, so my first question is: 1. Is there a way to update without losing that data? and 2. Since I am already running emunand 8.1.0-19U, can I just update from this to the latest one (via wifi), if I also update my gateway first?
