=head1 REFERENCE

The following is some reference material relating to certain in-game data
structures.

=head2 Option Fields Max Length

If the "Option Fields" are more than 1152 bytes altogether, Chip's Challenge
will crash when loading the level. The "Option Fields" include the following:

  Map Title
  Bear Trap Controls
  Cloning Machine Controls
  Map Password
  Map Hint
  Movement

Bear Trap Controls use 10 bytes for every link. Cloning Machine Controls use
8 bytes for every link. Map passwords use 7 bytes. Movement data uses 2 bytes
per entry.

In addition, bear traps, clone machines, and movement data use 2 bytes in
their headers.

=head2 Object Hex Codes

The two map layers on each level are 2D arrays of uppercase hexadecimal codes. Each of
these codes corresponds to a certain object that is placed at that location in the map.
This table outlines what each of these hex codes translates to, object-wise:
