My ROMs play fine but no matter what I do I can't get HLSL to work. I even downloaded a MAME 0.173 package that is specifically configured for HLSL (referenced in this youtube video: ). Any suggestions from those who are smarter and better at this than I am? Is it possible having DirectX 11 is the problem? Anyone have it working with DirectX 11? I'm on Windows 7 if that's any additional help. I would love to see those vintage scan lines on my LCD screen.
