ok ive got the game actually working now but when i go to attack a planet comes up with error 200 and sumtimes 216 plus after about 30-40 mins of gameplay it cuts out any idea how to fix that one =S

nope, try the compatabilty modes

compatability modes? i don't know what they are. sorry im not exactly smart when it comes to software in computers 🤣

Right click on the executable file -> properties.

Find compatibility mode somewhere in tabs and select "run this program with win95 compatibility".

I thought Windows ME didn't have compatibility modes. And Imperoum Galactica is apparently a DOS game anyway.

Could Error 200 be the old Runtime Error 200 bug caused by a too-fast CPU? In that case WinThrottle is the answer.
