Sega Virtua Fighter Double and triple image?

The work continues on the Virtua Fighter 1 Cab. The original Chassis had this issue where the Horizontal was squished, I replaced every regular and Horizontal cap and the Horizontal width coil so I gave up on it. The issue with the new chassis seems weirdly related but. Now I have double and triple images also squished.

I'm sure its a reasonable fix, but Im out of ideas atm.

The original Monitor and Chassis were sharp image. New Monitor is a Sharp with a Universal Chassis.

I can say for certain part of the issue is the Chassis is a 5PIN RGB+Ground+H/V. The old Chassis was a 6pin RGBEVH. First picture is The VF1 wired in with VH combined, though Ive tried just V and just H with the same result. Second is a PiHDMI>VGA>CGA so I know the chassis and Monitor are both fine.

vf is a medium res game(25k), the image looks like a medium res game being run on a standard res monitor
you can run the signal through a gbs8200 to get it to work, its probably cheapest option

Yeah that fixed it more or less, Since the GBS8200 is VGA DB15 output I connected the VGA output to GBS8100 that has a standard RGB 5pin output. I don't think thats necessary right? I should be able to just make a DBPIN to RGB 5pin adapter.

I'll admit I'm not crazy invested in this one I just wanted know why it wasn't working. If I can get it to work through a GBS8200 then I'll just put it in the backlog until a Medium res comes along or I can get the original CRT rejuvenated and the chassis repaired.

Thanks!

yeah sorry gbs8200 will only give a vga output, i do not know of anyway to get 25k to 15k
