I'm playing the original game on 1997 hardware in MS-DOS 6.22. I've progressed quite far into the game and have been saving after each race or rank increase in one of the 10 save slots available within the game. These are stored in \CARMA\DATA\SAVE with the corresponding save files named SAVE[0-9].
Because my progress has required more than the 10 saves allowed, what I've done is progressively moved the SAVE files to another directory e.g. CARMA\SAVEGAME\SET01 so that the 10 save slots are freed up to re-use again within the original SAVE directory.
So my archived files look something like this:
\CARMA\SAVEGAME\SET01\SAVE0 \CARMA\SAVEGAME\SET01\SAVE1 \CARMA\SAVEGAME\SET01\SAVE2 ... \CARMA\SAVEGAME\SET01\SAVE8 \CARMA\SAVEGAME\SET01\SAVE9 \CARMA\SAVEGAME\SET02\SAVE0 \CARMA\SAVEGAME\SET02\SAVE1 ...
The problem is when I move one of the sets of save game files back to the original \CARMA\DATA\SAVE directory, the game no longer recognises them and sees the 10 save slots within the game as "EMPTY". Is some form of encryption being applied to the save game files?
How can I get the game to recognise the save game files again once they've been moved out of the SAVE directory and back in again?
