I know the topic has already gotten underway, but I'd like to say that this idea is awesome. The thought of just being able to use the 3ds as a remote PC would just make me happy. Especially if you could just link the two over a network and still have the same functionality hundreds of miles away.
Technically, you could download and try the android dolphin emulator. You'd be living the dream, albeit at at about -2 fps
Any idea on how fast that would work on the OnePlus One? Don´t have one but was planning on getting one, and this would be a real nice iceing on the cake
