Cart Cap, L2 and R2 actuators

To be placed on a Freeplay CM3. You also need buttons; I used Adafruit's 8mm soft tac switches, [found here](https://www.adafruit.com/product/3101).

Drill 1-2mm holes just inside the screw posts for the leads to go through. Solder a pair of leads on one side to about 4" of light-gauge wire, fish through your holes, and super- or hot-glue the buttons to the GBA case's shoulders, then join to the board however you like (I did direct solder, but if you've got headers that'll fit, use those).
