# ZBA (working title)
|
||||
|
||||
A Game Boy Advance Emulator written in Zig ⚡!
|
||||
|
||||
## Scope
|
||||
I'm hardly the first to write a Game Boy Advance Emulator nor will I be the last. This project isn't going to compete with the GOATs like
|
||||
[mGBA](https://github.com/mgba-emu) or [NanoBoyAdvance](https://github.com/nba-emu/NanoBoyAdvance). There aren't any interesting
|
||||
ideas either like in [DSHBA](https://github.com/DenSinH/DSHBA).
|
||||
|
||||
This is a simple (read: incomplete) for-fun long-term project. I hope to get "mostly there", which to me means that I'm not missing any major hardware
|
||||
features and the set of possible improvements would be in memory timing or in UI/UX. With respect to that goal, here's what's outstanding:

## Usage
|
||||
|
||||
As it currently exists, ZBA is run from the terminal. In your console of choice, type `./zba --help` to see what you can do.
|
||||
|
||||
I typically find myself typing `./zba -b ./bin/bios.bin ./bin/test/suite.gba` to see how badly my "cool new feature" broke everything else.

Finally it's worth noting that ZBA uses a TOML config file it'll store in your OS's data directory. See `example.toml` to learn about the defaults and what exactly you can mess around with.

Be sure to provide SDL2 using:
|
||||
* Linux: Your distro's package manager
|
||||
* MacOS: ¯\\\_(ツ)_/¯
|

* Windows: [`vcpkg`](https://github.com/Microsoft/vcpkg) (install `sdl2:x64-windows`)
|

Be sure to provide SDL2 using:
|

`SDL.zig` will provide a helpful compile error if the zig compiler is unable to find SDL2.
