Also, I bet the Internet archive or exoDOS will have a perfect copy. The latter is a one click experience. Check the laws in your country for whether these are legal.
I know the last time I picked it up, there were a well respected set of patches from scient (a quick google pointed me to https://github.com/DrazharLn/scient-unofficial-smacx-patch ). Somewhere in here is a pre-done distribution you can just click and run with for modern windows.
The simplicity of early Civs with a modern, fully baked interface. Maybe with hexes instead of squares if that doesn't break the game. FreeCiv exists, but it doesn't feel modern either.
and you no longer can do nice square grid for your buildings or 90 degree positioning
With hexes, I like how you can move in any direction and see the same number of new tiles; with squares, you're compelled to walk in diagonals to see more stuff and it feels icky.
