Change game parameters:
 Note: This procedure requires editing a game file; creating a backup copy of
the file before proceeding is recommended. With a text editor, edit the
"player.ini", "player airplanes.ini" and "player guns.ini" files in the game
folder. In the "player.ini" file, find all the "rof" (rate of fire) entries and
change them from "3.5" to "35". In the "player airplanes.ini" file, change all
of the health entries by adding a few of zeros. Reduce the health values for the
enemy planes and enemy boats.
