I've got two old RFU adapters that are compatible with N64/Gamecube consoles... Both work, but one was missing the pin that actually connects into the back of the television's analog input jack. The other had a damaged head and I could not plug it into the analog input jack either.
On one, I sheared off the rubber and smaller copper wires, exposing the main copper wire beneath. I'm a complete novice with this kind of thing, but after no luck attempting to plug the copper wire directly into the analog input jack, I assume the smaller copper wires are actually needed.
At this point, both have the heads removed from the cable.
Any suggestions on this?
