Ideally, yes video and audio should be shielded. In reality, it makes little difference, look inside any arcade cab and tell me what you think of the wiring. Nothing is shielded, nothing is isolated.
One could utilise a third separated connector for video / audio, but then we're adding complexity and cost. An 8 pin mini DIN would probably work well.
As long as power wiring is adequate I think we'll be okay.
What I'm trying to achieve is a jamma extension cable with off the shelf parts, with minimal assembly. Just two PCBs, 2 x connectors to solder to each PCB and 1 x jamma connector to one of the PCBs. After that, all that's needed is to plug in 2 x cables. Very quick and no fuss way of producing jamma extenders.
What we need to find is cables that can be purchased pre-assembled and of the same length. They must contain identical connectors on each end, and have PCB mount connectors of the opposite gender available. The general data lines aren't as strict with requirements, power needs to be adequate to handle 15 Amps, video / audio may need screening?
So far the 30cm IDC cable and 30cm PCI cable is all I can find that fits the requirement. Open to suggestions if anyone can think of anything better. Oh and thinking about it, 50 pin IDC is overkill, I think 34 to 40 pin is more than enough.
