First, I tried to search for threads on this forum that might have answered this question but for some reason the forum search feature isn't working for me so sorry.
I'm trying to sell a Nintendo 3DS (regular size) that came bundled with an SD card and Super Mario 3D Land pre-installed. I usually format electronic devices before selling them online but this 3DS has a digital game that I didn't even play. How do I unlink all my accounts and personal information from this device but keep Mario 3D Land tied to this system so that the next user can create all his Nintendo accounts and still play the game?
These Nintendo accounts confuse me. Nintendo Network ID, ClubNintendo, eShop, Miiverse, etc.
<---- Edit: Wow, I've been a member for that long? Anyway, good to be back.
