I'm not sure if this idea has been proposed by anyone before, but I was thinking we could run exploits or homebrew on an updated 3DS via Download Play. I remember someone making a thread before about editing a Mario Kart 7 ROM with a custom track, and then went to download play, and the updated, non-hacked 3DS saw the ROM edit perfectly. That being said, I don't see why doing something else, like hiding an exploit, can't be possible. What do you guys think of this? Doable, impossible, or possible but very difficult?
