I solved the problem! It is a resolution/screen format that Mame is forcing (or maybe a driver problem) so that only a blank screen is displayed. I recommend this procedure for any similar issues going forward.
To fix, Right Click on the ROM, Choose "Properties", Display Tab, Change the 'rotation' drop down to "anti-clockwise", click "Apply" and then "OK". Then run the Rom and go into the game config menu (TAB). The Config menu will be on its side. Arrow down to "Video Options" and hit ENTER. Arrow down to "Rotate" and cycle thru until you see "None".
The Config menu stays awkwardly on its side, but the game will run upright and non-windowed.
