TµEE co.(TM) presents: Glass Braker MD


----------------------------------------------------------------------------
Introduction
----------------------------------------------------------------------------

This is my first game for my favourite video game system: Sega Mega Drive
(Genesis for North American people). The original PC version of this game is
Glass Breaker QB, like the name says its written in QB (not QBASIC !!!) plus
tiny amount of 386 optimized assembly. GBMD is not written in BASIC like its
PC counterpart, its written in 68K ASM and little in Z80 ASM.


----------------------------------------------------------------------------
Objective, enemies, hints
----------------------------------------------------------------------------

Objective of this game is to break all the windows on the house. It is not
the easiest task because the inhabitants don't let you do it so easily. You
will encounter 5 enemies, each level adds one.

First enemy is hyper active blind grampa who throws out slippers from a
broken window. Because he's blind, he doesn't know where you are and throws
them randomly at random windows that are broken.

Second enemy you'll encounter is a bird that keeps on trying to shit on you.
That bird flies slowly near the roof of the house and when it flies above
you, it drops a present aimed at your head.

Third enemy, the most pain of them all, is a killer kitty cat who tries to
scratch your ass of. NOTE: no other enemy likes kitty.

Fourth enemy is granny, she is ugly and she has a 2 barrel shot gun !!! Just
pass the door and granny will blast your head off if you don't pass the door
fast enough. NOTE: granny hates cats (she has allergy).

Fifth enemy is a UFO disquised as a cloud. Granny and gramps are its current
subjects and it will not let you harm them. UFO tries to cause you terrible
pain and suffering with a low charge protonic beams which are enough to make
you immobilised for days. NOTE: Cats have much weaker body than you.

Try to break upper windows before lower ones and also aim while you move.
If you have taken care of all the windows, you'll complete the level. If
you have better time than in TOP players list you will get the honor of
entering your name and being in the list yourself. This game hides some
sectrets in it, you have to do certain actions at certain point of the game
to reveal them... NOTE: most keyboards don't allow you to open secrets, use
gamepad like I do ;) Anyone who finds all the secrets and developes for
MD/Genny can have the FULL source of this game !!!


----------------------------------------------------------------------------
Thing you should know
----------------------------------------------------------------------------

This game runs only on European systems with 3 or 6 button controllers. You
will see lockout screen if you run this game on non European system. This
game is timed to be used with 50Hz machine and it uses 320x240 resolution
which immediately makes this game incompatible with NTSC.
EDIT: I added 60Hz compatibility now.
If you happen to see "Back-up RAM error", it means, that SRAM is not present
or compatible with this game. This error is very unlikely to happen if your
cartridge uses "standard" (what most games and emulator use) SRAM accessing
technique. Directly readable/writable SRAM method is supported.

+ Added provisions to support flashcarts that do not have SRAM. Writing to them can cause lockups.

+ Made some of the code a little bit more readable, holy hell what was I thinking when I wrote it LOL
