Step 9
The joystick board appears the be the brains of this operation, it's packed solid with silicon and switches. And two big ol' springs for the XY/AB buttons—probably so they're not too stiff, or too soft, but juuuust right. Teardown Update: After some further research and a burn from the soldering iron, we learned that these springs are meant to close the capacitive sensing circuit used in the buttons.
