Videos
The video files C205.QMV, C213.QMV, and C227.QMV through C233.QMV actually have nothing to do with the game. For example, C213.QMV is of two people sitting around while Castles III scrolls on a computer in the background, and C227.QMV is of a (modern) family. To view them, copy them as C220.QMV (make a backup of the original C220.QMV first) and wait for a province to revolt.
