Ok so I an selling a 3DS XL with a game pre installed. What I'm wondering is if anyone knows if I can remove my Nintendo Eshop ID from the 3DS but still keep the game installed.

Obviously I have sold this console and stated that the game is pre installed. So I just need to know if it's possible to remove my details but still keep the game On the system.

Nintendo really seem to like causing a lot of hassle when you want to sell their systems.

Any help would be appreciated.
