Direct contact DOES NOT work for Nintendo Ds Lite. You are stuck using LM386. I and many other people have tried, it doesn't work. There is a tutorial on how to install the IC to get sound reactive leds.

And to get to the speakers just remove the four screws hidden by the pads on the upper half of the ds, and slide the clear part of the casing away from the DS. You will see the speakers.
