Untested I made this a while ago so people to use it to rgb mod thier tv’s easily. It is based on this https://hackaday.io/project/170807-darthclouds-retro-gaming-room/log/175650-jvc-av-32920-crt-rgb-mod that was on shmups and uses the jungle chip injection. All the credit to them. I have not used it and do not know if it is 100% correct. Make at your own risk.
