Calculator:	TI-83
File size: 	2666
Version:	1.2
Released:	02-08-1999

This TI-83 game require SOS or AShell.

This game was first made with Ti8xbas. I have now rewritten most
parts in ASM to optimize the code. I haven't released the code 
earlier because it was so bad. Now it's a little better but it's 
quite hard to understand when nothing is commented :-(

All the else and for labels are from Ti8xbas and I didn't bother
to rename them.

If anybody would like to port this to TI-82 and other calcs I would 
be very happy.
---------------------------------------------------------------
VERSION HISTORY

v1.2	Decreased the sizes with 332 bytes. I have now gone through the
	code several times and optimized. Thanks Joe W. for many tips
	about optimizing. 

	Removed the bug that made the ship go slower up.

	

v1.1	Decreased the sized with 418 bytes by rewriting some code from
	Ti8xbas to asm. Now 2988 bytes.	

	New random generator that works much better. This made
	the game alot harder.

	Add lives. You now have 3 lives instead of 1.

	New intro logo. This decreased sized alot when the pic is not
	the whole screen, now just the logo.

1) Make sure you have SOS or Ashell installed on your calculator
2) Send STARSHIP.83P to your Ti-83
3) Run SOS or Ashell, then run "Starship Commander 1.2"

GAMEPLAY

Level 1:
Avoid the alien ships and collect diamonds. Have to collect
20 diamonds to finish level.

Level 2:
Fly trough the hole in the brickwall without hitting the wall.
20 walls to continue to next level.

Level 3:
Shoot the comets so they don't hit the earth. Don't let any comet
get past you or hit you. Fire with 2ND. When 20 comets are hit your
mission is success and earth is saved.

(Wow what a new and original storyline :-) )

--------------------------------------------------------------
BUGS / STRANGE THINGS

The spaceship can be go trough an alien spaceship without hitting.
(This makes the game easier :-(  ).

You can only fire on shot at a time on the third level so have to hit on
the first shot. 

--------------------------------------------------------------
FUTURE PLANS

Still a lot of thing to fix:
1) High score
2) More levels
3) Teacher key
