Almost there - I have everything setup the way I want it, however Mame games are not quite displaying in fullscreen. There is about an inch border on the top and bottom of the game. I ran Mame in command line separately to see if the problem persists, and it does. Attached is a screenshot of a game, they all do the same thing.
When running the command line, I get the following message - Warning: layout view 'Bezel Artwork' contains deprecated bezel element
Is there a switch that might override this issue? When running a game without the bezel, it does stretch to the top and bottom of the screen properly.
