So I got the GamePad PCB two weekends ago and I’ve putting off the soldering and test for a bit and finally got to it this weekend. It looks like all the button clicks and whatnots are working well and I just need to wait for the powerstrip PCBs to arrive now. Here’s the demo game in Pyxel working in conjunction with the joystick.

Now all that’s left is the launcher for starting/selecting the games and crimping in all the power connections.
