;
; + you can have upto FOUR multiples! (~20 pixels apart)
; * some optimizations: keycall, menu handling, port nops removed,
; # slow enemies (including pickups) didn't always appear (just 25-50%)
; + enemies can fire different kinds of bullets: aiming, double, triple
; * maximum number of bullets increased (48 for enemies, 128 for you)
+; * beamweapon can be selected when you got laser (like vice versa)
+; * selecting laser removes tailbeam or up-double
+; # tail beam/up-double correctly centered
+; # disappearing bullets (when enemies fired multiple bullets) fixed
+; + bullets and lasers both upgradable upto level 9
+; # fixed end story (_vputs didn't recognize 0-end when "'" in string)
+; # stars couldn't be altered anymore since recent levelformat changes
+; * maximum different enemies increased from 28 to 63
+; * pickup sprite altered, small changes to some enemies
+; + new moves implemented: 75% speed and lure-while-moving
+; # 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
+; some time (shield halves damage and absorbs bullets in normal mode)
+; + 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
+; * enemy sprite pointers stored as words (thus increasing sprite table
+; length from 768B to 65kB, and increasing sprite calculation speed)
+; * hardcore mode does _more_ than doubled damage (bulletsdamage +1)
