Yes that is the correct cable. What you describe is very similar to my setup.Lots of people using OSSC, but I was going to run this minigun through my gscartsw into my framemeister. Due to the wording on the https://retro-access.com/collection...aflex-8-pin-mini-din-rgb-scart-cable-for-mods cable, I am concerned. Is this still the correct cable I need?
