Pico Compatibility?

[Slypty]

Wanted to say thanks a ton for creating this Project, I've built a bunch of Sticks off this design and implemented them into 3D printed Arcade Shells, everyone seems to love the PFB.

I've always used the 4M RP2040 with castellated edges, most recently I decided to try the 16M version and some headers instead. I flashed the RP2040 with the latest version, and for some reason I have no response at all from my stick or any buttons. Maybe I washed the board too much, but wanted to check there's no compatibility issues with using the 16M RP2040s? Thanks again

The issue is that the RP2040's I bought have a slightly different pinout. In place of GP4 this design uses 'G' on Pins 6 and 13. Look out for boards labelled with 'G' on them, they are tied to VSys Ground internally. So once it's placed into the PFB, these contacts short out and make the board non-functional. These boards have the 4-pin debugger layout at the bottom instead of the standard 3.
