+; # fixed the enemy aiming bullets procedure
+; * enemies fire their bullets centered too! (even the large bosses)
+; * you may NOT have any multiples together with beams, just lasers
+; + added new enemy guns: quad- and 6x-fire!!
+; * sprite table length increased to 768 bytes (stored DIV3)
+; + ships 3/4 select hardcore mode: score and damage are doubled
+; + first icon not only increases armor, but also activates shield for

+; + ship selection screen also shows ship specs (hardcore/tailbeam/etc)
+; * shield looks different for each ship
+; * hiscore/savegame procedure optimized (several bytes smaller)
+; + B<>W mode setting will be stored

+; length from 768B to 65kB, and increasing sprite calculation speed)
+; * hardcore mode does _more_ than doubled damage (bulletsdamage +1)
+; * 10 bytes off by optimizing main menu a little
+; * and optimizations to hiscore name handling saved another 17 bytes!
+; * score increased by 1 per placed enemy, instead of time (otherwise

+; # prevents exploding more than once (not dieing while inside ground)
+; * some unneccessary pushes removed
+; + final boss also fires moving mines (just up/down-enemies)
+; * on collision less damage to enemy, more to you (bosses too simple)
+; * normal pickups will increase armor and shield directly (no [alpha])
+; + a large pickup'll appear at the end of a level which will select
+; your next upgrade: beamweapon, laser, multiple/tailbeam/up-double
+; + a small explosion is displayed when enemy's hit but not destroyed
+; # _all_ multiples appear at your position at start of level
+; # bug in selecting multiples fixed (recent bug)
+; + getting passed 3rd upgrade (4 pickups) increases score by 250!
+; - second icon integrated in 5th, first two icons removed (unused now)
+; * the armor bar is now 5 pixels in height; very visible
+; # if selecting upgrade or starting level, charge bar wasn't displayed
+;
+; 1.00.C21 -- 21.XII.00 -- size 6797
+;
+; * armor-bar background, empty upgrades sprites changed
+; + shows sprite when laser hits an enemy (his "shield"?)
+; + exit-key also quits out of ship selection screen
+; # fixed direct-quit on death bug (bug since recent optimization)
+; * armor-bar background changed (more elegant and smaller code)
+; # "flash" when end-boss spawns mine fixed
+; + enemy's y start position can be specified per enemy
+; + when bullets selected, upgrade icons won't appear half the time
+; # remainder pixels in armor bar (appeared after heavy damage) removed
+; + your ship's explosion is now also 8 frames (half enemy expl. speed)
+; + does NOT display Done after running in TI-OS! (anti-teacher ;)
+; * storyline completed (probably the crappiest story ever!)
+; # only first byte of ship's sprite altered; now loads whole word
+; - tail beam removed (up double only); odd ships now contain laser
+; # fixed laserbeam display when firing at right edge
+; # star relocation altered to work correctly w/ new screen location
+; # halfluring wasn't 50% (more like 75%) since random enemy spawning
+; * restored multiples for bullets (since it's unlikely you'll select 1)
+; # fixed mem overlapping causing "weird stuff" when moving multiples
+; # bullets fired below screen bottom are moved up onto screen
+; + SOURCE ALSO TI-83 COMPATIBLE (still few bugs like hiscore, bullets)
+; # upgrading beam weapon removed multiples
+; # clipping at left side wrong in TI-83 version fixed
