To change the cd rom file, open it with notepad, and you will see the letter "D" there, just change this to "C" (then close notepad/save the change) and the game works ....

Great game
but I still think the 1st one is best, perhaps even better than UFO!! (XCom 1)
Does the sound work only in Dos box?
Btw I just downloaded Twilight 2000 from the underdogs, any opinions on it ?
