sprocketnes is an emulator for the Nintendo Entertainment System written in the Rust programming language.
Its purpose is to serve as a technology demonstration to show how the Rust programming language is suitable for systems software such as emulators. It has many shortcomings and is not intended to be a production-quality emulator.
sprocketnes is also designed to be a relatively clean example codebase, showing off various Rust idioms.
The NES was chosen for this project because:
It's familiar to most hackers.
It's a reasonably simple system to emulate.
Because of its popularity, its workings are relatively well-documented.
It's CPU-bound, so it can serve as a benchmark to help optimize Rust code.
The audio requires some measure of real-time operation, which tests Rust's real-time capabilities.
The main controls are as follows:
Select: Right shift
Save state: S
Load state: L
If you want to build
sprocketnes, you will first need the Speex codec library installed; on the Mac you can install it with
brew install speex.
To build (add
--release if you actually want playable speed):
There are numerous demos and games available for free for use with this emulator at http://nesdev.com/.
