FIXED - I think I've tried everything and still cannot get Scanlines in Mame

Thank you!  I just did a new build and for the life of me couldn’t figure this out.  Interestingly I just did a build prior but installed directx because SFIV needed it.

Add me to the list of thanks. Just put together a kick ass little NUC build for a vertical cabaret cabinet build and this was driving me nuts.

Just hit this problem myself on a rebuild with a fresh Windows 11 install. Here is a Reddit thread discussing it as well that contains some links for the DirectX downloads. Glad I found this thread because it set me down the right path to finally solving the problem.
