Rockman or RetroRain: for info on how to convert the mapper!
Disch: for his mapper docs and a better MMC5 startup and a new bankswitch code!
abw: for a lot of info!

Changes for this version 1.1a:
I had no idea that the game will not start because I think I messed up the bankswitch
code.

Changes for this version 1.1:
Fixed a bug that causes the script in battle while the monster drop a treasure chest.
Example: The monster name will show a Slime have drop a chest, but it's actually
a Army Crab that actually droped the chest. This bug have been fixed. It might be the
old bankswitch code that was causing it. His new bankswitch code fixed this bug.
