Kicad module & footprint: Just import the lib & mod file from the zipped file.

Hi,
My update from the scanned PCB...
Unfortunately, there's only the front side.
You had to meticulously check the real PCB, to update this project...
Note: The connector width had to be adjust to the real socket.

Wow! This is impressive.
One comment, the cartridge seems to be too wide and it would not fit into the slot.
There are no contacts on the other side because sockets are single sided. See photos.
