A while ago I bought a Friends of Nintendo Humble Bundle, which came with quite a few codes. I still have the codes, as I couldn't find a way through the 3DS to redeem the games without installing them immediately. This is troublesome, as the first one I downloaded was Street Fighter IV, which took up quite a lot of my available blocks, and I am keen to play it for now! Although I could just redeem the code, install the game and then uninstall it, this takes up some time and can be a bit of a nuisance.
I was wondering if there was a way to redeem these codes and not install them, so I can just go to my download software page and install them whenever I want at a later date, similar to how Steam handles the game library.
