libretro-rs

Getting started

A reference implementation is available in the example folder, and should be enough to get you started. At a high level, you need to modify your Cargo.toml:

[dependencies]
libretro_rs = "0.1"

[lib]
crate-type = ["cdylib"]

Then implement a trait and call a macro:

use libretro_rs::*;

struct Emulator {
  // ...
}

impl RetroCore for Emulator {
  // ...
}

libretro_core!(Emulator);

et voilà! Running cargo build will produce a shared library (.so, .dll, etc) that you can use with a libretro front-end:

$ retroarch --verbose -L libemulator.so /path/to/game.rom
