>>28229154You can recuperate it but it's a fucking pain in the ass thanks to Nintendo's stupid account system
Basically you phone them and ask them to unlink the NNID from the old console for X reason then they ask you stuff about the account (your location, purchases, DOB, email) then you either have to provide the serial number of the new console or, the long way if you buy second hand and the serial is worn off, create a second NNID so the serial of your console get uploaded to their database and can finally link the old account with the new 3ds
Seriously, fuck Nintendo.
