Emulato.rs

A collection of emulators that I've created to learn the internals of old gaming consoles.

Emulated Systems

• CHIP-8
  • 8-bit virtual machine for very simple games.
  • Complete and functioning implementation, except for sound.
• Game Boy
  • Everyone's favorite 8-bit handheld console from the 90's.
  • Implementation is still work in progress. While some games work well enough to be playable, others suffer from graphical glitches or even random crashes on unimplemented features. Already passes a large part of the mooneye test ROMs, but notably those tests related to the Game Boy's timers are still failing. The audio processing unit is not emulated yet, so no sound for now.

Usage

You can use Rust's cargo build tool to run the emulators. See

cargo run --release -- --help

for an overview of available command line options. Each emulator sub-command has its own --help message with the arguments it accepts.

To run a given ROM file in the Game Boy emulator, you can run

cargo run --release -- gameboy <path_to_rom_file>
