It's not actually my own source.
Here's my situation:

I have a decompiled version of Adventure which will compile in DASM, unlike
the original Decompilation I found on the internet somewhere.   What I would
like to do is eliminate extra code (black and white switch code and stuff)
and free up space for more Graphics storage...

The thing is, adventure is designed in more of a game engine format, so it
draws it's graphics in a loop of sorts, pulling the graphics locations out
of a table which just stored the High and Low bytes of the graphic location.
At the end of each set of graphic bytes is a Null terminator thing, $00
which signals the last byte in the graphic definition.   Therefore the
graphics are actually accessed by their start location in memory without the
ability to use Line Tags.    I hope that made sense.. :-)  It allows for the
program to draw all the graphics with the same block of code by simply
walking through a table of values.

What I would like to do is eliminate all the wasted code space and move it
all to the bottom of my application, it should easilly allow me enough room
to add a large boss image or something.   And hopefully some additional maze

Thank you for your time.
