I had two NES consoles RGB modded back in 2020. I am selling this one. I originally planned to keep it, but it sits unused most of the time. It uses an 8-pin mini din out adapter that has 3.5 mm auxiliary integrated. Unfortunately, I’m not able to get pictures of it set up and working in my current location, but it does for sure work. I only have one of these eight pin RGB cables, so only the power cable is supplied. There is slight yellowing on the front of the console, but otherwise it is in good shape.
