New Birch's Briefcase With Fully Custom Starters by Archie and Mudskip

Setup

To apply these changes you have two options, either pull the branch from the TeamAqua fork of pokeemerald (instructions below), or copy in the changes by hand Here is the diff

This branch should be Expansion compatible.

Usage

Just create a script and use callnative to call the UI, make sure to waitstate afterwards. Like this:

YourEventScript::
   .... the beginning of your script
   callnative StartNewPokeballCaseUI
   waitstate
   .... the rest of your script

How do I pull a feature branch?

You use git remote add and git pull commands to pull in a feature branch. That is,

git remote add team_aqua https://github.com/TeamAquasHideout/pokeemerald

git pull team_aqua birch_case
