Ok. Gotta ask:
What on EARTH are you using for a video card?
iirc it was the direct x which prompted me to shelve it. Regardless, at the time I couldn’t find a card that was compatible. I’ve never revisited the matter.
I would LOVE to play again!
Check out dosgames.com.
I only have one computer that it will not run on, and that’s my newest, a Dell I9 XPS 32gb ram. I’ve played it on every box I’ve had since 1996 or so. Remember to run it under DOSBox. I’ve never had any video issues at all.
If you’re on a PC get a Nvidia geforce 2800 or better. Runs MSFS 2024 very nice with awesome frame rate.
