I bought a 25 dollar rgb amplifier with wiring on eBay and installed it today. Terrible soldering but it works fine. The mod allows you to buy a RGB scart cable and then hook that into the console and either a scart tv or a scart to hdmi converter. I am doing the same on my Genesis 3. The picture is much much better than composite. Composite introduces terrible artifacts and waviness in straight lines.
See pics.
I have better pics on my phone and will upload tomorrow.
