1) Pull repo

2) Run Battle-System\src\Defines\generation\stringsToCharArray first. It generates strings.h file

3) Compile this XSE script. Do not put a #dyn offset:

    #org 0x168CD2
    msgbox 0x8740050 MSG_NORMAL '"testing battle."
    callasm 0x88014C5
    end

    #org 0x740050
    = testing battle.

4) In battle_init.c, scroll all the way down to the "z_battle_setup()" function. In the function body there are some settings you can tweak for testing purposes. I've hardcodded a certain battle setting, you can change something like "b_config->type = SINGLE_TRAINER;" to another battle setting. Battle_types.h has the defined settings.

5) Run Battle_system/src/build and then run Battle_system/src/insert. These are both python programs. Alternatively I made some quick shell scripts compile and debug. You'll need to edit the file paths though

6) Open in VBA, and talk to the TV in the player's room :D
