# Build and usage
|
|
|
|
The following instructions build the `rba-sdl2` target which is currently the main platform. (`rba-minifb` is also available without audio support)
|
|
|
|
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
|
|
Download SDL2 runtime binaries for windows (either 32bit or 64bit depending on the target machine)
|
|
https://www.libsdl.org/download-2.0.php
|
|
https://www.libsdl.org/projects/SDL_image/
|
|
|
|
Extract all the DLLs into the project root (Yeah, its dirty and a build script will be written in the future to automate this)
|
|
|
|
## 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 -- 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.
|
|
|
|

# Why is this project needed ?
|
|
|
|
It's actually **not**. There are quite a lot of GBA emulators, ~~and even some written in rust~~. Actually, I couldn't find any game capable emulators written in rust.
|
|
|
|
I'm only doing this as a side project intended for learning rust.
|
|
|
|
This is my *third* take on this project. My first go at this was about 3 years ago, but I didn't like rust much at the time so it got abandoned.
|
|
I tried to resurrect it a year ago but didn't have the time to get invested in a side-project, let alone learning rust.
|
|
|
|
I've grown to like rust a lot since then, so here we go again.
|
|
You know what they say, *third time's a charm*.
