Adding RGB to a Composite only CRT TV

Well here in USA, RGB didn't work out because the physical interface was never agreed on. Our few odd TVs that accept it may use varying connectors. SCART, BNC, or otherwise.

 

OK. I got it to work ^_^

Problem was, I did not ground the megadrive -_-

Everything else was grounded, except for that.

I also added in a 1.5 kilo ohm resistor, and tied the sync ground high.
Technically that would short circuit it, but it gave me perfect colour.
