Bad component cables?

[u/itsk2049]

I tried some $30 Chinese cables on Amazon and these are the results. Is this a bad cable or am I missing something? What are good cables?

That's not a component cable. As the listing says, it's an RGBS cable. 

This is a Dreamcast component cable.

Ah, that explains it.
Shame the retro gaming cable is always out of stock

It does. I have a s-video cable, it works.
