So I used rxtools 2.7 a couple of years ago to make it so I don't have to insert a cartridge into my 3ds and had all of my gamers on my microsd card. I haven't touched my 3ds in a year but with sun &mmon coming out soon I assumed I'd need to update my 3ds to play it... So my question is how do i backup my saves and move to whatever the latest/most stable cfw is , with rxtools I had to go to a website everytime which sucked.
