Title: sega genesis
Post by: TH0R on January 07, 2009, 03:10:52 PM

i was looking at an rgb mod for this and it just neede a wire to be made with din connec. on one end, and scart on the other, av cable was thrown in ther also, it plugged into the genesis audio jack. can this be done by hooking up an rgb and av to the 8 pin din connecter and still have the same results? thanks

Yes.

nice...think it could work with an rgb modded duo?

Well if I got what you're trying to do right then really all you're doing is taking the right signals and feeding them to where they need to go.  So if you have the system outputting RGB and audio just get those signals from somewhere and wire them to what you want.  As long as the output is going to something that can take it as input then you're set.

Here are two different tutorials on making scart leads for your Genesis model 1 and 2. Not very difficult.

I finished my genesis rgb mod tonight:

RGB+sync, composite video, stereo audio. Just hooked them up to the pins on the din connector. I had to put a 220uF capacitor and a 75 ohm resistor on each of the RGB+sync lines though. More info:

nice job. i was wondering about those resistors... and how i can hook them up with this component cable mod, or if it's  needed

I just soldered them like this:

wire --> resistor --> capacitor --> output

Add a bit of heatshrink tubing and it will be nice and snug. The only problem is finding room for them if you're doing to do it inside the scart connector itself.
