Playing DS game on 3DS: drawbacks

[gumby_trucker]

isn't the 3DS a multi-core system?

I wonder if you could have one core emulating the DS and the other adding some top-level OS stuff like pausing etc. without interfering with the flawless b/c. They could make it so that when you press the Home button the system tells the game that the DS has been folded shut, so it would automatically pause itself. Then the other core could offer some additional features like wifi for spot-pass or Internet browsing etc.

I'm guessing this is how Wii U will handle Wii b/c, by running on only some of the cores and either shutting down the rest or using them for something else.
