Created an integer palette fade in/out in Allegro 4 and am feeling *unreasonably* happy about it.
This oughta be very easy with modern shader stuff even in truecolor or even HDR, honestly. But even with 8-bit, doing saturating decrements down to zero means the darkness swoops into the image in pools, leaving the brightest spots until last: it gives an HDR-like effect on early '90s hardware. And is era-appropriate, unlike floating-point equal interpolation/big black semitransparent GL quad.
I wonder if Masto can handle this...it's a DOSBox-captured video, so it's native-res, using the Zip Motion Block Video codec. ffplay can play it right; VLC screws up the palette entirely.
Hah, no, "failed validation", I can't attach it at all. But, surprise, YouTube actually can!
I mean it's probably transcoded it into fuzzy VP9 or something, but. :P
