Select the 'shaders_slang' > 'crt' > then the 'mame_hlsl.slangp' file (which is close to the bottom).
Then in the 'Shader Parameters' option change:
TATE Mode - 1
Scanline Jitter - 1
Scanline Crawl - 1
NTSC Frame Jitter Offset - .1
Scanline Amount - .35
Overall Scanline Scale - 1.2

After that, then save it as a preset.
It's fairly studdle and only adds to the character of those generations of games.
