TV output

Hi everybody.
   New guy here. Long time tinkerer, amateur programmer and NES homebrew enthusiast.

Anyway, I picked up a DMG-01 Gameboy for about 7 bucks the other day and got the mod bug. One thing I've always wanted was composite video output from original GB hardware (yes I'm aware of the Super GB and the Wide Boy, I was around in the 90's.) Ive stumbled upon a few things in my research.

This unit was found in many a Gameboy Retail Kiosk in the early 90's

According to this site
These units contained dual NES/Famicom motherboards. Like on the Super GB , it once again required piggybacking off another console's hardware.
The Demo Boy, seems to be the same thing

This next one

is a mystery to me. I've only found this one picture of it. It looks a bit smaller than the Demo Vision, but I'm not sure whats going on inside.

I would like to find a way to tap the original GB hardware between the PPU and the LCD and send it out to the television. I assume I would have to build some custom conversion circuitry. Can anyone provide any info on the subject matter. My ultimate goal is to convert my GB into a home console.

Re: TV output

There's Rival-Corp's mod which went viral. … adapter-2/

There's also this:

I think there are a couple othe rprojects, but I can't find them now. If you can find them, there's of course the GBA Transverter and GBA TV Converter. But they've been out of production for a while, so good luck with that.

There's also this if you're willing to pay a lot:
