Don't know how to take a pic of the screen. I hit f12 but doesn't show the whole screen. Tried to take a screen shot but it's all black. In moon patrol it has the black borders on the side and just a little black on the top and bottom like the one you posted. This pc has an on board graphics card nothing else. This is noticeable in moon patrol while other games do fill but still has a slight black border on the top and bottom like in burger time. All the settings are default in mame.
