It was also suggested long ago that an emulator could handle flicker with
a venetian-blinds effect.  Draw one frame on every other scanline (every
Atari scanline; every other VGA scanline), then the next frame on the
interleaved frames.  The visual quality would be questionable, but it
would surely be easier to code and run faster than faking phosphor
persistence, and for this I think would certainly be less
headache-inducing than flicker.

(If one of the emulators supports this already, ignore me; I haven't been
keeping up to date on them. :) )
