I'm in the process of MAMEing a cabinet for a friend of mine and one part of the project is giving me problems.
The cabinet is a Global VR Golf and there is a lighted instruction card between the speakers, as seen here:

We've removed the card and now have an opening that is 10" x 5". In it's place, my friend has mounted a 15" LCD monitor (12" x 9").

What I need to figure out is how to restrict the screen size from 12x9 to 10x5 (obviously not the same screen ratio). That or I need a program that will display an image and remember the window position. I will use CPwizard to create the instruction images, then resize them, and hopefully get them to display in the same position every time. I need to find a program that will launch the image file from a command line. My searches haven't gone well. Even if I have to display the image full screen on the secondary display, that's fine, because I can add borders to all the images to fill in the hidden areas if needed.
But I'm not sure the best way to go overall. I want the button layout to load the moment a game is started and stay loaded the whole time.
Anyone have some ideas on what to do here? Thanks.
