Advanced arm cannon palette changes samus's arm cannon palette depending on beam combination.
In addition this patch also adds a beam glow effect on samus when shooting a beam projectile while charge beam is equipped.

There are 2 patch variants: BASIC and OPTIONS.
BASIC just changes arm cannon palette based on beams equipped.
OPTIONS has the same changes as BASIC and also adds the possibility to change the arm cannon
(and beam palettes) with palette presets. It adds 2 new options in the special settings:
- "Cannon Color Setting": moves you to a seperate menu where you can change the cannon color with presets.
- "Apply Color To Beam": applies an unique beam palette to all beam variations based on the cannon palette.

This patch uses freespace $85D000 until the end of bank $85 by default and some in bank $9B for arm cannon palettes.
If you use the OPTIONS patch it also uses freespace in bank $90 for beam palettes, which can be put anywhere in the ROM, too.
