Don't be scared. 3DS softmodding is as safe as it can get. And you will find help here for almost every software problem.Ah that is good to know.
As you may notice I am very scared to mess up this 3ds.
normally if I f... something up I would be like bummer but hey not the end of the world, but with the 3ds I am scared because my daughter would hate if it breaks.
You and your daughter: Have fun with a modded 3DS.
