Build Status Crates.io

Overview

Port of reSID, a MOS6581 SID emulator engine, to Rust.

Story

This project originated from zinc64, a Commodore 64 emulator, around Jan 2017. It evolved to the point where it can be useful to others working on C64 sound/emulation so it is packaged and shipped as a standalone crate.

Usage

Once SID register read/writes are wired up to resid, all that is left to do is to generate audio samples and push them to audio output buffer.

while delta > 0 {
    let (samples, next_delta) = self.resid.sample(delta, &mut buffer[..], 1);
    let mut output = self.sound_buffer.lock().unwrap();
    for i in 0..samples {
        output.write(buffer[i]);
    }
    delta = next_delta;
}

Changelog

  • 0.3 - compliance with the original resid
  • 0.4 - full sampler support
  • 0.5 - closed performance gap largely due to resampling
  • 0.6 - SIMD optimization
  • 0.7 - continuous integration and GPLv3
  • 0.8 - documentation and api refinements/internal cleanup
  • 0.9 - migration to Rust 2018
  • 1.0 - no_std support
  • 1.1 - more idiomatic implementation, removes interior mutability and improves support for async rust

Credits

  • Thanks to Dag Lem for his reSID implementation
  • Thanks to Daniel Collin for motivating me to put this out and helping out with code optimization
  • Commodore folks for building an iconic 8-bit machine
  • Rust developers for providing an incredible language to develop in
