“This instructable will show you how to create a simple shield for Arduino DUE to interface a genuine arcade machine with low resolution CRT and jamma connector to your PC. The shield main pourposes are: to amplify the video signal coming off the video card (too low for a genuine Arcade CRT monitor); to protect the low resolution CRT monitor from out of frequency sync signals; to “translate” button presses on arcade control panel to something the PC can handle. Notice: the shield DOES NOT force the video sync signal to low frequencies: you are in the need for some specific software for that. I suggest you to use CRT emudrivers or Soft15KHz.”
