Changing calculations for Hit, Avoid and Dodge

I’m interested in changing how the GBA games (specifically FE7) calculates Hit, Avoid and Dodge to being more like how FE14 does it; with Hit/Avoid being (Skl/Spd * 3 + Lck) / 2, and Dodge being Lck / 2. Does anyone know how to change this? I have a hex editor so if it’s something simple like finding where that data is and what bytes need changing, I can follow easily.

It’s not that simple; you’ll need to learn some assembly, then modify the battle routines (which isn’t that hard, but a hex editor isn’t going to be enough).

Jump on the discord if you want to learn assembly, the link’s floating around somewhere. The Ultimate Tutorial also has a good, if outdated, primer for ASM.
