IIRC MAME uses those shaders.
I'm not much interested in matching the features in reshade's CRT shader (if I wanted that, I'd just use reshade's shader and be done with it), FBA's CRT simulation has its own trajectory. IMO, curved screen is a neat gimmick, but nothing more (and I was there long before reshade). In the mean time, see the WIP thread for upcoming updates.
