Batsugun PCB video issue

Post by thchardcore »

Hi,

I have an original Batsugun PCB I am using with an Xrgb-1 and Xrgb-2. In both cases, the video exhibits a weird curve on the bottom left edge of the picture. I am using a sync strike to output the video from a supergun directly to a vga CRT. I do not recall any issue with the pcb when used directly on my arcade cabinet, but no longer have access to it at the moment to test.

Has anyone experienced anything similar to what I am describing. My other pubs including battle garegga do not exhibit this behavior.

Thanks

Sounds like theissue fudoh identified so very long ago:

There's a ntsc AFC setting to put this right somewhere. More observations 1/3 way down in here:

Or try bumping the xrgb thread?

Sorry for vagueness just joining the dots, don't have an xrgb myself :)
