Hey ya. For me to get MAME to do what you don't want to do on my widescreen lcd, I had to add it to the command line of MAME. Maybe you have added it in there? Can I see your MAME command line arguments? You can also pass the resolution you want it to use by typing -r WxH or make it do a clean stretch which keeps it from stretching from edge to edge by using this: -cs auto, which is what I use at home. Or, to fill the screen completely, you can pass this argument: -hws to stretch it to full screen, or -nohws to NOT fill the screen and keep your original aspect ratio. Hope that helps Lucas. Haven't seen ya in a while.
