so my friend has some backed up saves from games he downloaded on the eshop. Only thing is he lost the 3ds, called nintendo to unlink the nnid, registered that nnid with a new 3ds he bought, then found the lost 3ds but he wants to get some of the saves back. The 3ds with the saves is a n3ds 10.6 that i can downgrade (hoping it doesn't brick). Is there any way possible to get those saves back?
