This is my Black Sheep Squadron I have been working on,  I was able to get the game running fully on the rom after a lot of trial and error, there are issues with this rom and the Bally.vbs.  The first time you start the table hit F6 set the dip switches, ON put a check, OFF leave blank, close and restart pinmame F3 and they will be set, there are a couple switches that are your choice but the others have to be set correctly  for the table to work.  I recommend the 3 ball with alternating bumper lights. Thanks go to Randr for the bumper ring scripting, and all the great talents that keep pushing the limits of VP enjoy.
