Version 2.0.4 PM contains over 180 changes from 2.0.3; most, you will be unaware of but several are significant:
The raison d'etre for this edition is the new superfast PowerMacs (over 90mhz), which up to now, have those ships out there skittering around like water bugs. We've added a governor which should keep speeds within limits regardless of the machine it runs on.
Saving a copy of the game
Put the "Saved Game" folder into your DRUMBEAT Folder.
By copying and renaming the small (18k) "Saved Game" folder, you can save a copy of the game at any point.
Since the program always looks for a folder called "Saved Game", you must first trash (or rename) the original, and then change the name of the copy back to "Saved Game" in order for the program to recognize it.
Handy, if two or more people wish to maintain separate games on the same computer.
