# Build and usage (Desktop Application)
|
|
|
|
To get started, you need to get a [stable rust toolchain](https://rustup.rs).
|
|
|
|
## Linux build dependencies
|
|
Install SDL2 dependencies
|
|
|
|
```bash
|
|
sudo apt-get -y install libsdl2-dev libsdl2-image-dev
|
|
```
|
|
|
|
## Windows build dependencies
|
|
SDL2 runtime binaries are included in this repository, no extra setup needed.
|
|
|
|
## Build & Usage
|
|
You need to obtain a gba bios binary.
|
|
An [open source GBA bios](https://github.com/Nebuleon/ReGBA/blob/master/bios/gba_bios.bin) is also available and supported.
|
|
|
|
|
|
Place the bios file in the repository root and name it `gba_bios.bin` (or alternatively use the `-b` command line option)
|
|
|
|
|
|
Build and run in release mode (performance is terrible in the `dev` profile)
|
|
```bash
|
|
$ cargo run --release -p rustboyadvance-sdl2 -- path/to/rom
|
|
```
|
|
|
|
|
|
You can also drag&drop rom files or any zip files containing `.gba` files inside into the emulator window and a new rom will be loaded.
|
|
|
|
## Key bindings
|
|
|
|
> Currently the key bindings are not configureable.
|
|
|
|

Special key bindings
|
|
| Key | Function |
|
|
|-------------- |-------------------- |
|
|
| Space (hold) | Disable 60fps cap |
|
|
| F1 | Custom debugger (requires --features debugger) |
|
|
| F2 | Spawn gdbserver (experimetnal, requires --features gdb) |
|
|
| F5 | Save snapshot file |
|
|
| F9 | Load snapshot file |
|
|
|
|
|
|
# Android Application
|
|
|
|
The android project is placed inside `platform/android`.
|
|
To build it, open it with Android Studio.
|
|
|
|
You also need to set up rust to build android targets with NDK.
