CopperBoy

CopperBoy is an Arduboy emulator written in Rust.

Status

Although this project is in a Work in Progress status, currently the emulator is capable of playing many of the ArduBoy games at full speed. You can find a nice game collection in eried's ArduboyCollection.

• Running ArduBoy games in .hex format.
• The full AVR ISA is implemented.
• Not all atmega32u4 hardware is implemented. I've been implementing what the games I tested needed to work.
• Sound is fully working.

Usage

Currently there's an SDL frontend included in the emulator.

Building

First you need to install the sdl2 and sdl2_ttf libraries with your operating system's package manager.

Then you can build the rust binary:

./ci/build-bin.sh sdl linux-gnu-x86_64

Running

You can run the emulator with cargo:

./target/x86_64-unknown-linux-gnu/release/sdl ROM_PATH
