Battle RAM

This is a list of the RAM locations used by the battle program. The code that uses this data is split into two modules. The first module is the battle module, which controls the battle itself (damage calculations, monster A.I., etc.). The code for the battle module is in the first half of bank C2. The second module is the battle graphics module, which controls all visual aspects of the battle (animations, menus, cursors, etc.). The code for the battle graphics module is in bank C1 and the second half of bank C2.
