gameboy-rs

A classic Gameboy emulator written in Rust.

Passes all the Blargg's CPU behavior tests.

Some unique features

Tests

I provide a whole slew of CPU bahavior tests in testdata/ that will allow you to test your own emulator. All you have to do is read in testdata/cpu.json or testdata/cpu.yaml and convert it to your internal structures in your own emulator.

You then can set the pre state and then compare to the post state. Check test_runner_json() in lib/cpu.rs for an example.

An electron GUI

I have an expiermental electron GUI, but still not sure if it's fast enough for the job. It works though.

Rust version

This is the last known rust version it works with: rustc 1.12.0-nightly (545a3a94f 2016-08-04)
