NES(-101) Toploader RGB backplate (MegaDrive/Genesis 2 + mini-din 8)

Simple backplate replacement, allowing for either a mini-din or megadrive/genesis 2 socket to be installed.

I used this one, because it has a nice breakout board with it (did have to file to top flush a little bit); https://www.consolesunleashed.com/product/sega-master-system-model-2-av-connector-breakout-mod-kit/
