I wish to learn, in depth, the ASM coding behind the GBA games. Any resources to get me started?

I want to make my own hack that includes some features from other Fire Emblem games, such as skills from the Tellius series. In order to do this, I want to learn my own ASM coding so that I can be more flexible with how I program these various features. Any documentation on things like the battle routine, how units are handled in the game’s memory, anything will be useful.

Well, you’ve certainly come to the right place! Here is a good intro to thumb assembly, which is most of what you’ll be using (THUMB is a subset of ARM assembly, which is also used in the game, but by the time you need to mess with anything involving ARM you’ll probably be able to figure things out by yourself). Here is a thread detailing the battle routine. The discord is a good place to get help, as well. Pretty much everything you’ll need (and more) can be found in the Unified Hacking Dropbox.

Looking forward to seeing what you come up with!

Thank you! What is the community Discord?

I leave that as an exercise to the reader.

Hint: We have a very robust search function.

I am indeed a fool. See ya around!
