I also have older stand alone games from the late 90s and early 00s in fact some are on 144 floppy drives like doom and Duke nukem etc
I don't have that many on floppy. maybe dozen or so early games like Microprose type games. I do still have dos 6.22 though. i've been tempted to get an old pc, maybe 386/486 to play some of my old games rather than having to use Dos box etc.
Have all my 8 and 16 bit machines for most of retro stuff
