On the real pcb, when the "15 Khz" dip switches is on, the game runs on 15 Khz "fine".
When the game starts (after the self test), the graphics don't fit on the screen (they are too big to fit), but there are no sync problems.
You cannot adjust the width and height on the monitor to see all graphics.
Don't know it I explain me clearly, I am sorry.
I think this revision handles this.
