I haven't been able to run this "sim" in quite some time. It never worked right under Windows 7, and in Windows 10 the game speed was crazy and the full-screen never looked right. Worked great in my Windows 95 and Windows 98 days, and I had a lot of fun with it so I still kept my local copy installed. Well I finally was able to find a good fix:https://github.com/narzoul/DDrawCompat/releases/tag/v0.4.0
Go there, and extract the ddraw.dll file from the zip to where you have your game installed. I then created a config file called DDrawCompat.ini in the game directory along side the ddraw.dll file and added these lines:
FpsLimiter = msgloop(30)
FullscreenMode = exclusive
I also set my Windows Desktop res to 800x600 before launching, and set the compatibility mode to Win 98 and 8-bit (256 color). I can play her again at long last!
