For some reason mame32 doesn't have 640x432 availible in the resolution box on my computer. I have an ATI radeon 9550. I have seen pictures on the internet of people setting their resolution to 640x432 in the resolution box. I can set windows to this resolution so i know my video card supports it. Mame32 skips from 640x400 to 640x480. How do i get 640x432 to appear in resolution drop down box in the default options? Any ideas?
