## Development

### Requirements

* This project has the same requirements as [Butano](https://github.com/GValiente/butano), follow getting started instructions [here](https://gvaliente.github.io/butano/getting_started.html).

    * GBA Emulator (using [mGBA](https://mgba.io/) for this project).

    * [devkitARM](https://devkitpro.org/wiki/Getting_Started).

    * Python (use [pyenv](https://github.com/pyenv-win/pyenv-win)).

    * [Butano](https://github.com/GValiente/butano) (imported as a submodule).

### Extra Tools Used

* [Usenti](https://www.coranac.com/projects/usenti/) for sprite editing in format supported by the GBA.

* [VS Code](https://code.visualstudio.com/) used as IDE, this repo contains configuration to use it.

#### Guides Used 

* [Butano Getting Started](https://gvaliente.github.io/butano/getting_started.html).

* [GDB Debugging with mGBA](https://felixjones.co.uk/mgba_gdb/vscode.html).

* [Embedding emulator on itch.io](https://www.matthughson.com/2020/07/17/nesdev-embedding-an-emulator-on-itch-io/).

* Help from the lovely folks in the gbadev Discord.

### Build / Debug

1. Clone the repo and `cd` into it.

2. `git submodule update --init` to pull Butano submodule.

3. `cd` into `src` this is where the actual GBA project is stored.

3. `make -j$(nproc)` to build using the makefile.

4. Open the output `.gba` file with your emulator to play.

#### Debugging:

* The `.elf` file contains all the debug symbols, run this to debug.

    * This is what is launched by VSCode debugging, specified in launch.json.

* If you want a better debugging experience you can play in the Makefile.

    * Set USERFLAGS to `-Og` to disable most optimisations.
