I don't know, if the topic allready exists...
But I edited my mame.ini file to make use of HLSL,
But when I boot up a mame game in Attract Mode it doesn't use the HLSL...
The only thing I would like for HLSL are the Scanlines.
I switch of Bilinair Filtering, and use Scanlines.... but the scanlines just doesn't work, when trying to enable them in Attract
