Video Cable Pinout
S-video is available on the port. The controller uses the same common N64 controller pinout, so you can plug in a real N64 controller but you need to power it from an external source.

S-Video Signal
The multiplayer box is passing-through the S-video signal, but unfortunately the cable that goes between the iQue and that box does not pass the S-Video signal, so to use the multiplayer box with s-video you would need to modify that cable.
