Ok, I currently have a 3ds. Although, I am wishing to sell that one and purchase an aquablue one.(3ds) I do not want to send any data ( Activity log, streetpass, photos, sound recordings, etc) except for my ambassador games. Is there a way to put your sd card in your laptop and find the game folder, save it, buy new 3ds, and put it in the new 3ds's sd card. (Sorry if you dont understand).
OR can I format the entire 3ds, go to nintendo support, and check if im eligible to obtain the 3ds games.
If there are other ways please tell me.
Thanks 
Note: Im 12 so keep this pretty simple please
