Wait, what?
I'm sorry, I'm confused.
Nvm, it resolved itself. Dual Destinies was supposed to be due out at midnight earlier today, and when I woke up to purchase the game, it was still unavailable. So I looked around to see if there was some different process for downloading non-1st party new 3DS games (up till now, the only game I downloaded was from the virtual console) and a FAQ guide mentioned either scanning the game's QR Code or getting the download code from participating retailers, which was when I made this thread because I was just as confused by the FAQ as you are by what I initially asked. Then after looking around a bit more, it turned out that Capcom had postponed release of the game until noon, at which time I was able to do what I initially thought I could do--download the game directly from the eShop.
So yeah. Nvm.
