This is a library for making games on the Game Boy Advance using the Rust
programming language. It attempts to be a high level abstraction over the
internal workings of the Game Boy Advance whilst still being high performance
and memory efficient.
The documentation for the latest release can be found on
[docs.rs](https://docs.rs/agb/latest/agb/). Note that this repository does not
2021-07-07 07:09:33 +10:00
necessarily contain the latest release, but in development versions. Further work
2021-06-04 03:55:42 +10:00
is needed to improve the documentation.

## Build Requirements
2021-03-07 04:58:59 +11:00
* Recent rustup, see [the rust website](https://www.rust-lang.org/tools/install)
for instructions for your operating system.
* You can update rustup with `rustup update`, or using your package manager
if you obtained rustup in this way.

* arm eabi binutils
* Debian and derivatives: `sudo apt install binutils-arm-none-eabi`
* Arch Linux and derivatives: `pacman -S arm-none-eabi-binutils`
* Windows can apparently use the [GNU Arm Embedded
Toolchain](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads).
Make sure to select "Add path to environment variable" during the install.
* This process has only been tested on Ubuntu and Arch Linux.

## Test Requirements
* libelf and cmake
* Debian and derivatives: `sudo apt install libelf-dev cmake`
* Arch Linux and derivatives: `pacman -S libelf cmake`
* mgba-test-runner
* Run `cargo install --path mgba-test-runner` inside this directory
## Real Hardware Build
* Need gbafix, rust implementation can be installed with `cargo install gbafix`.
* On compiled elf file, additionally need to
```bash
arm-none-eabi-objcopy -O binary {input-elf} {output-gba}
gbafix {output-gba}
```

## Stability
0% stable, I have no problems making drastic changes in the API in order to make
something nice to work with.
