I have setup a scanline effect that works in 4x3 games like Metal Slug and Ninja Baseball Bat Man if I use the d3d renderer. I only get the effect on 4x3 games with all vertical games not showing it. Now my only guess is that MAME doesnt use filters on none integer scaled games, but if that is the case is there anyway for me to get vertical games to show them as well? My next step in switching over from classic MAME is to start fixing the video modes on all my games but I can't find much info on setting up vertical games on a horizontal screen.
