Nice! My Model2A harness has a voltmeter on CN5 line. (CN5 is mainly used to connect GND.)

Recently I added 1000 ohms resistor to CSYNC line just in case. This note gave me the idea. I don't know the best resistance value but 1000 ohm works with OSSC VGA input.

Basically, I agree with you. My CGA to VGA adapter should work. OK, I found the picture of mine. It looks like components are almost the same as yours, but, in fact, the quality is pretty poor. I've measured the resistance of potentiometers and found that range of resistance is up to 200ohm...

Custom PCB looks nice! I am new to electronics so there may be mistakes. Let me explain a little more. CGA to VGA adapter Potentiometers cause a lot of noise on the image, so I set all them to 0ohm. (the adapter was very cheap lol) Caps on the adapter are bypass caps connected to GND...

Finally got the flawless image! Here are what I did. Shielding SuperGun from EMI First, I shielded my SuperGun with aluminum foil. Diagonal lines were weaken. I guess radiated noise from the PSU or the MODEL2 cage (or both) interfere the SuperGun. RGB to VGA adapter Then I created this...

Thank you so much for your various ideas. I'd wired PSU-ground, PSU-rack, cage-ground and cage-rack, but there was no improvement. When I connect other JAMMA boards to my supergun, no noticeable lines appear. So I suspect that my MODEL2 board has some trouble but I'm not fully confident that...

I got it. I use a SuperGun with the JAMMA. PSU - MODEL2A - JAMMA harness - SuperGun(CBOX USB v2) - RGB SCART - OSSC - HD60 X (capture)

Thank you, so it could happen to other boards than mine. I'll try to tie the earth pin and a metal rack. I hope it will work.

No. But HD60 X (Video Capture Device) resizes the input when capturing the video. e.g. 496x384 -> 640x480 I can see lines on both captured image and passthrough video on the display.

Hello, I recently got a DEAD OR ALIVE MODEL 2 A-CRX board. It’s working well, but I’ve noticed diagonal lines appearing in the video. My wiring: PSU - MODEL2A - JAMMA harness - SuperGun(CBOX USB v2) - RGB SCART - OSSC - HD60 X (capture) I confirmed that the PSU output is clean. Lines are...
