Hi I just was wondering if there is something like this out there as I regulary repair 3ds systems this could really help me when I send my 3ds to nintendo (In 2013 because of a broken sd card slot ) I got a erased "Game" I played on that date that only shows as ??? now. Thats why Im beliving that something like this could be out there but I sadly cant find anything about it / like it on the web a bit of information would be nice
