Hey folks, I'm trying to write a patch for Imzogelmo's color coded MP digits, to temporarily set the Reflect palette back to it's normal green-yellow for the duration the Reflect barrier is shown. I'm calling a routine that's basically a copy of Lenophis' Bad Decoration function to reset the palette at $7FF8-$7FFF, except I've inserted reflect's original four-color palette into free space and it's loading that instead.
It works, and much like Crusader, it overwrites previously-Reflect's-now-actually-MP-numerals palette for the rest of the battle. So naturally, I figured I'd combine this with Bad Decoration. However, from what I can tell, the Bad Decoration code is called multiple times every frame (during animations) and undoes any changes to Reflect's palette. I'm at a loss as to where to call my code from so that the palette changes last throughout Reflect's animation. I don't know exactly how Crusader does it.
I'm currently hooking C1/C9A5, as that is called by Reflect to play the "ping" sound. It's reached via C1/C884 (X = 8B) much in the same way Crusader is (X = 67).
Another approach may be to modify Bad Decoration so that it only calls the code to restore the palette once Crusader/Reflect has finished their animations, but I don't know where to hook Leno's code either.
Here's my code. Also, please find attached the code for Bad Decoration and Color-coded MP Digits (which I've taken the liberty to disassemble and comment for my own understanding).
