MAME artwork - Can the screen be moved down?

[Random24]

Is it possible to move the game screen down using the lay files? I have tried a number of different settings and it always puts the game in the middle of my monitor. When I try to change the "y=" in the bounds section of the screen area it just changes the relative position of all the other elements, not the location of the game on the monitor.

I have been out of the mame scene for about 8 years and am updating my cabinet with a 9:16 monitor to replace the s-video TV that it has used since 1999. Because of the new geometry I am trying to use as much of the screen as I can with marquees and instruction cards.

The issue is that with many games the marquee plus to part of the bezel is taking up all of the space above the game (and sometimes overlapping) while the bottom is often left blank.

If I can find a way to move the game screen to a lower position on my monitor that problem would go away.

I am using MAME 0.183 on Linux Mint 18.1 so any ideas will have to not include windows applications.

I think I figured it out. I was using the crop artwork option and that was messing up the layout. I have started manually cropping the bezels and disabling artwork crop in mame. Now everything is looking good.
