B in Wild Battles Moves the Cursor to Run

On the Fight, Bag, Pokemon, Run menu, pressing B will move the cursor to Run as long as the battle type isn't BATTLE_TYPE_TRAINER.

Build Instructions

See here for the prequisites and help in installing them.

Cloning the repo

Open your terminal to whatever folder you want to download this repo into. Then, do the following to download the repo and build the included tools:

$ git clone https://github.com/VentDystopic/bpre-b-wildbattle-run.git
$ cd bpre-b-wildbatle-run

Adding your ROM

Copy your ROM to this directory and rename it BPRE.gba.

Where to insert

You can specify it by updating the definition of START_AT in config.mk.

If the given address is acceptable (i.e. is word-aligned and has enough bytes of free space), it will be inserted there. Otherwise, it will just use START_AT to determine where in the ROM it should start looking for free space.

Building the project itself

Once you're ready, run the following to build the project:

make

This won't actually modify BPRE.gba, instead your output will be in build/rom.gba. Naturally, test it in an emulator.
