FS Parts: R-Type Filter board

The old nintendo cabinets had an EMF cage. Big metal contraption. You would slide the PCB inside and then this filter board would connect to the board on the inside, then push onto the one opening on the cage and you would fully enclose your PCB while having the connections passed through to the other side.

Not necessarily needed. You could run the board directly from the harness with no filter board/cage, or do what I did and use the cage but just leave the filter board off.

My guess is someone just wanted it for completeness.
