Real CRT and MAME HLSL/BGFX doesn't do the same thing. Real CRT have control over the color lines brightness while MAME can't do. There is a big different between those two.

Have to be emulated correctly or else not gonna look right on the fading and come back.

Now you see why I turn that off. Better than have those look incorrect with rainbows showing.
