Minor thing - DOS games didn’t always necessarily use non-square pixels. Many did, but some (Jazz Jackrabbit springs to mind) did not. It was down to the fact that if you displayed a 320x200 image, the CRT would stretch it out to 4:3, giving you slightly taller pixels.
I read a really good blog post about it years ago, but I can’t seem to find it right now.
