Instructions
Instructions are in the script. Pretty much set the game variable ID and set battle themes based on the value of the variable ID.

FAQ
Awaiting question.

Compatibility
I'm not sure if it's SDK compatible. It aliases Spriteset_Battle's initialize method.

Credits and Thanks
If it weren't for JoeYoung's original "Individual Troop Themes" request, I wouldn't have worked on this script.
Lowell helping me out in terms of explaining this.

Author's Notes
After working on Individual Troop Themes, I wanted to work on this script. I was pretty bored so yeah.

Terms and Conditions
Credit me, please? :3
