This is the top side of the controller, which contains regular switches, buttons, and one joystick, but any button with a substandard label is connected to a special pin on the board, which will perform one or more actions:

• Nothing
• Shuffle button mapping
• Activate shockers
• Activate LEDs

I'm thinking of doing the same with VR controllers too, because those people really enjoy playing Beat Saber and I hate that.

(I'm joking)
