I've just discovered this hardware, RGB-Pi.

https://www.rgb-pi.com

This is an RGB Scart cable that plugs directly into the 40pin expansion port on a Raspberry Pi. This then combined with their own Linux based OS, called RGB-Pi OS, based on Raspian and Retroarch, and designed and configured to run in the lower arcade resolution of 240p, including Retroarch configured to run at this lower resolution.

This is designed for those wishing to get a perfect original retro image on a CRT TV via emulation. Quite a cool idea.

I was actually hoping this was something slightly different when I first discovered it. That you would be able to feed an RGB signal via this cable into the RPi, and it to upscale and output via the hdmi port. That could really reduce the cost of upscalers. This isn't that.
