Any cable would work just fine as long as it is well shielded, Unlike speaker wires, interconnects are very sensitive to noise but the good news is they are high impedance wires so the copper wire doesn't have to be thick, So two important things to consider, Better shielding and keep them as short as possible to reduce interference.
Monster cable made some good S-Video cables back in the day that they were selling for $75, those are available now for under $10
on eBay, you should get a pair of those, See if you can find RCA cables made by monster from back in that era too.
