This is an unfinished disassembly of Super Mario RPG’s bank $C2, or the “battle bank.” Some background info, Super Mario RPG uses a custom scripting language, a lot of which is located in this bank. Additionally, you can find a lot of where the battle stuff happens (like the battle script command’s functions) and all the battle data transferred between monsters and Mario’s party.

This document is an expansion of Giangurgolo’s $C2 bank disassembly (he’s the author of the SMRPG editor LazyShell). In the expanded document, it lays out all the pointers for the animation script commands and battle script commands, what happens when an ally’s turn starts, what happens when a monster or ally hits each other, among other things.

There should be enough here for anyone that is willing to make their own custom status ailments/buffs, new stats, change existing script command function, and even more.
