In the final release, the wrong CRC causes rewriting of some wars with the default values. But there was message "You got a checksum error today, but that doesn't mean you have to like it!" that appears when CRC is wrong and then jump to the game ending. Seems this stuff was made to prevent from cheating for level select or some other parameters.
