I have an error 20 that shows up when I boot the arcade machine. I read on the internet that if I turn of the Force Feed back It will go away. I did turn it off on the menu screen, Did the Initialize test on the steering, pedals and light. And the game works. Is my FFB PCB is going bad or the motor in the steering wheel. Need help to understand this one, thanks. I also read this just in case https://wmexpressway.net/index.php?showtopic=34253&st=50 and this Help with Namco Steering Force Feedback Board (WMMT1/2 and Mario Kart 1/2)
