I'm impressed with the results from your lo-tech batch file approach. The output is really quite nice.
It turns out that real CRTs also have a number of user-adjustable parameters, which of course makes it impossible to define any sort of "canonical" or most-accurate preset. :)
(Like this weird paper-white monochrome CRT that uses P7 phosphor, designed for 350-line MDA but can also handle a greyscale 15.7khz 200-line CGA input... the scanlines are so sharp that it looks 100% fake!)
I'd still like to give it enough flexibility so that a preset can at least be accurate to a particular mode of operation. I actually went down the rabbit hole of looking up a precise persistence curve for the P39 phosphor (as used in the IBM 5151) - found conflicting data, but a friend will be helping out with a video and an ad-hoc program to get some results, so we'll see!

Yup, multisync/multi-scan sure complicates things. :)
