As much as I enjoy this game, I find both with and without CRT simulation to be imperfect because what I’d really like is CRT simulation… but with a slider to reduce the picture tube curvature a bit.
It’s just too extreme to be comfortable for me. (I know my childhood 21” CRT TV wasn’t that extreme, nor did any of the 14”, 15”, or 17” monitors I used along the way from an IBM PC XT through to my modern PC feel that extreme. (The 17” ones, which I still have, are those late-era Viewsonic flat-tube ones with no curvature at all… though I think the PC XT had MDA, not CGA, which would have made it an apples-to-oranges comparison what with the text-only display.)
I’m going to experiment with moving it from my Linux PC to the Windows 7 SP1 machine “on the new end of” my retro-hobby LAN and applying something like ReShade, but it seems a shame to use such a major hack-around when you poured so much work into it.
