MAME border

[surtr]

Is there a way to have mame create a simple, 1 pixel border around a game?  On my setup, I have the screen mounted behind smoked plexi so the game image just shows up "floating" in the middle of the front of the cab -- unfortunately, when playing games like joust, I cannot tell where the edge of the playing field is, so would like to surround the game screen with something like a 1 pixel gray line. 

Thanks!

Off the top of my head i don't see why not. It would be no different than a pre-made bezel for a given game. You would just have to play around in photoshop until you created the right size bezel to your liking
