Neo Geo MV1FZ + Mak Strike Supergun + XRGBFM - Video noise.

[GAINAX]

Recently purchased a Supergun from Arcade forge to go with my neo geo MV1FZ board:

Hooking it all up to my Framemeister I had some horrible video interference. The image noise is like a wavy snowy pattern that seems to be more prevalent on brighter images.

I'm using a shielded RGB cable from retrogaming cables UK, which has been fine for other stuff in the past.

Here's a video of the issue:

Any help would be much appreciated!

Have you tested with any other boards? If so, does the issue persist?

I've tried another MVS board, the MV1C, and I had the same issue.
