Theme code question...

I was curious so... I bought Xenoblade Chronicles 3D for my New 3DS XL as pre-owned with warranty at GameStop. Sadly, the one I bought was only a cartridge. But that's OK. :) I was wondering if you guys have any leftover codes for the theme that was supposed to include with the game. 🙂

A theme code can be found in the cover or at the eShop on a receipt.
