So here is a simple step by step I made on how to make AV cables for your Sega Mega Drive 2, GENESIS 2 & 3, Nomad or CDX console, you can even use these method for your Sega Saturn RF Unit. It could with others, if you use these method and it works for another console, let me know and I will add it on.
Stereo Sound?
Some 3rd party RF units have the right pins to output in stereo sound however the official Sega RF Unit only has the pins to output in mono. Confirmed stereo supported 3rd Party RF units include Pelican. If your TV does not have a auto Mono mode then you need to join the audio wires in order to create dual mono cables.
Things you will need.
. Sega RF Unit for Sega Mega Drive 2, GENESIS 2 & 3, Nomad, CDX or Saturn.
You can use 3rd party RF units, but the colors of the cables may not be the same as this guide.
. Set of composite cables
. Soldering iron
. Electrical tape
Step 1 - Getting it all ready
The first thing you are going to want to do is to cut the cable on your RF unit, just before the RF switch box (Giving us as much room to work with as possible).
You are now going to want to cut the tips off your 3 RCA plugs, only on one side so that you have 3 plugs on one side, and nothing on the other.
Next we want to strip all the wires that on the RCA cables, we first have to cut away at the plastic cover to reveal a wire covered in colored plastic (the color will depend on the color of the plug) , this is our signal wire and a copper wire that is around it, our grounding wire. We want to separate the grounding wire from out signal wire. (it helps to twist the grounding wire.) Do the same for all 3 wires.
Next we want to strip the wires on a RF unit cable, much the same we first want to strip away the outer plastic cover to reveal our red, white and yellow signal wires along with a copper grounding wire. Then strip away the ends of the signal wires so there copper is showing.
That's it for step one, the hard part is over.
Step 2 - Soldering the wires
Next what we want to do is pair the wires off, white to white, red to red, yellow to yellow and copper to copper (We want to join all 3 of the rca copper grounding wires together to make 1 grounding 1) once paired off twist them together and make a solid the 3 signal wires together.
Cut away the excess wire if you like
Use electrical tape around each of the 3 newly soldered joins, finally twisting the two copper grounding wires together. Now use electrical tape to cover up everything we just did, and we now have a working Composite cable for our console.
Step 3 - Adding some SEGA Flair
Now while the cable will work in its current state, it a) doesn't look that good and b) can be damaged easily. Well to fix both of these issues we are going to open up the RF unit we had like so with a screw driver, trying our hardest not to snap to clips on the inside.
Now we just place the taped section inside the RF box, and snap shut. Done, now not only do you have a cable that looks awesome, the connection is safe inside the plastic casing, as well as having a awesome retro look. The finished product should look something like this.
Step 4 - Back to gaming
Plug it in and let the good times roll, the picture quality is a massive boost over the RF unit, the colors have taken a very big leap forward. Hopefully you have everything you need to perform this at your house all ready, you just scored a free visual upgrade for your Genesis.
Hope this helps people.
