This patch primarily modifies the level layouts, screen updates, and some high level gameplay functions.  

1.  Title screen and story text have been updated
2.  The players' remaining life count now has 2 digits instead of one
3. Max life count has been increase to 7E (hex, or 126 decimal)
4.  I needed a 'question mark' tile, so I removed the 'copyright' tile and replaced it with a 'question mark'
5.  All 6 levels' layouts/palletes/spawn locations have been updated
6.  POW 'HELP' animation is half as long.  POWs walk (now they run) twice as fast
7.  Level 3 LASER enemy function has changed.  this was necessary to keep in this patch due to the level layout.
8.  Level 3 main weapon power up star does not instantly appear if you destroy a parked jeep with a star under it.  you must shoot it again.
9.  Minor tile graphic updates (parking space tiles) for Level 3 and 6.
10.  Screen repeat function added: To increase the length of the game, i added the ability to repeat screens (e.g. longer bridges (level 3), large swamp area (level 4), etc.).
	This function reads from a table located at 1D78C in the .NES file
	(if you wish to change it, the levels are in asending order, but the screens are in descending order.  values of 81-ff and 0 will not repeat.  values of 1-80 will repeat the screen that number of times)
11. The helipad palette update tables were unnecessarily large.  These were truncated to make room for more code.  no funtional change.
12. The rate at which the helipad lights flash was been increased
13. The helipad lights are designed to start flashing at a certain screen and stop flashing at a certain screen.  These values have been updated.
	These are also available for edit in the level editor
14. enemy spawn locations have been designed to be able to be randomized.  see the level editor for details.
15. Small enemy behvoir changes to fit the new level layout (like the level 3 large boats movement frames)
	Level 4 boss helicopter drops enemies of ID 4 instead of ID 1.  These are both infantry, but ID 4 can walk in swamp.  ID 1 cannot.
16. B/W missiles (Level 4 and 6) now give points for destroying them
16. Level 6 escalator direction is reversed.  also fixed the issue where the jeep is moved during death animations
