Is there any workaround to make the game start without the disc?

I lost mine and I still need to conquer Russia. (XD)

If you don't know how, than could you tell me where save files are? Like the games you save, so I could try to get it going through one of those.

The game CAN function without the disc I know that for a fact since you can take it out while your playing.

"Officially", no.

The game uses the CD as a check at startup, to be sure you have a valid, purchased game. Once that has been verified, you can remove the disc.

And info on finding a no-cd crack will not be given in these forums.
