Two questions:
1. when you trade it in, do you need to bring it in the box, with everything that came with it (i.e. instruction manual, that little nintendo magazine promotion pamphlet, etc.) or do you just need to bring the charger????
2. Do they even bother to turn it on??? I've been having a problem with my top screen (I have to push and hold the L button down to see the top screen, or else it will fade and not work properly..), and I'd rather not have to spend $50+ on repair to Scarborough through Nintendo.
