Looks like I forgot to change the potentiometer footprint. The one I selected in the BOM list looks to be smaller than the current footprint. I'm hoping the pads are big enough because I've already ordered the PCB!
05/03/2019:
I've added two jumpers to the PCB so that the AT27C256R can be programmed from the cartridge.

The very first version of the PCB came in the mail today.

I've added an adapter board to go from the EPROM on the GBDSO cart (PLCC32) to a PDIP28. See the AT27C256R datasheet for the connections.

The first version of the PCB doesn't fit in a game shell. I forgot the notch at the top right corner.
The PCB is also thicker (1.6mm) than an official game (1mm).

I want to show how the board is plugged in the adapter board.
For this I need to import the board into FreeCAD so I can do some 3D stuff.
I always got an exception error when trying to load the tracks from the kicad_pcb file with the KiCAD StepUp mod for FreeCAD.
The full length of the error can be viewed in the Report View under View>Panels.
The exception fault came from the make_custom function. This function is called from make_shape and make_shape is called from make_pads.
I printed the shape to the console and it did circle, rectangle, etc. fine but the first custom shape that it tried to make triggered the exception.
By bypassing the make_shape function when a shape is custom, using a simple if shape <> "custom":, I could then load everything without errors in FreeCAD.
I found the custom shapes by comparing the FreeCAD PCB and the KiCAD PCB. There were 6 custom pads in the PCB. They're used in the footprint for the audio jack.
I changed those footprints from custom to rectangle and could load the PCB and it's tracks without a hitch.
I had submitted an issue to easyw, but it seems like the problem came from the pads I had used in my footprints.
