^ Yep. That´s wath I did with RE: Revelations demo. But remember that in sleep mode, it  stills consuming battery (obviously not as much as in normal mode). So charge the battery every night (or something) to keep it, because if it offs, you´ll lose one start up... pay atention to the blue led.

-The good thing is that 3DS allows you to stop the game and go internet from the menu, and then you can resume it. It will be great to search for tutorials and guides.
