Talon Soft's Rising Sun - didn't work on modern hardware had to use VM or era hardware. If you want an updated port, you'll have to go to "https://www.slitherine.com/game/john-tillers-campaign-series" and buy a copy there.
WWII Iwo Jima - same as above (appears to be shovelware since it haphazardly uses the lithtech engine in its infancy.) ValuSoft / 3LV 2001 hilarious animations btw, don't play it
C&C Red Alert Arsenal - used OpenRA which is awesome!
