My Green Beret has stuttering video all of a sudden. It sort of slows down every half second, hard to explain.

Does anyone else have this issue? Or know why mine might be doing this?

Ah! Literally just worked out the issue.

If I set the analog video v-pos to anything over 2 it starts this stutter. Set to 0, and it's smooth as silk.

Any idea why this would happen?

I’ve got a strange problem with Green Beret (Rush N Attack) in that when I press F12 when using my CRT, the screen goes blank. When viewing via HDMI, the menu appears as it should.

Any ideas?
