First of all welcome to FEU.
You might want to check this:
Dance AI has already been done, from what I remember it uses some leftover stuff the game had for the actual dance target selection but don’t quote me on that:
The person that has been doing the most AI stuff is @Teraspark I would say, so if Tera can share his stuff with you or give you pointers on what he’s doing maybe that would help.
You can check this, but I’m not sure how up to date it is:
I would assume that the action to perform uses the same stuff as what we call the action struct, if it’s not just the same to begin with.
This is found at 0x203A958, you can find more on it in Teq’s better notes:
Finally, we have a channel dedicated to helping people that are starting out with gba assembly over at the discord server, as well as a channel for more advanced code discussion and other technical stuff. You probably want to join if you want to share your process and ask for help and whatnot.
