This is an Ethernet port which the RGB, GND, and +5v are wired to. PURE RGB, just to be clear, there is no converter of any type, no component, composite, or svideo. If you want those, you'd have to add something like a JROK.
I will post pictures of the console itself once I get home.
Here are pictures of the difference in output though.
Lol you guys, you're killing me. You guys think ethernet cables are special? they're just a bunch of wires in a nice little connector. I chose cause it looks so much neater, nicer, and more modern than that janky din connectors.
It depends on what you're using it for if you need the amp or not. I didn't need it when connecting to my arcade monitor, but I did when connecting to a JROK.
