I'm not a very smart person, and that translates in the fact that I didn't knew about Club Nintendo until after the Mewtwo DLC for Smash Bros. was announced. Granted, I now have such an account and have since linked it to my 3DS. However, since I did this after purchasing Super Smash Bros for 3DS (Digital), it is not currently registered in my products. I am planing to buy a physical copy of Smash Bros for Wii U sometime this week to register that one as well, but I was wondering: can I still register my digital Smash for 3DS onto my Club Nintendo account? How? Do I need to buy another copy of Smash for 3DS just to register it and qualify for the Mewtwo DLC?
If I can still register digital games purchased prior to the account linking, well, that'd be great, since I also have a Pokemon Y purchased before making the CN account.
Many thanks in advance~
