So yesterday I went and hacked my little brother's 3DS. He's only 9 so I obviously don't have full trust that he won't go into applications like FBI and screw something up. Of course I have NAND backups and put the applications in a folder saying do not touch at the very back of the home menu but I'm still wondering if there is a way or something that has been created to block a few specific apps. From what I know there isn't.
