COCO-8

COCO-8 (or 👻-8) is a fantasy VM for games and creative coding. COCO-8 runs on Wasm and it's written in Rust.

COCO-8 is made of these parts:

• coco-core, the virtual CPU. It is basically Uxn, as documented (COCO-8 follows the documented spec, not the reference implementation of Uxn).

• Devices, which interface with the CPU and provide input / output with peripherals or other systems (e.g. video, audio, controller input, etc.).

• A web-based GUI, for users to load and run COCO-8 roms.

Build and run

Requirements

You need Rust and Cargo in your system. You can get them with rustup.

You will also need the wasm-bindgen CLI tool.

Build

cargo install wasm-bindgen-cli

The build.sh shell script builds the Rust code and generates ESM modules inside coco-ui/vendor.

./build.sh

Run

To run COCO-8, you just need to start a local web server in coco-ui.

If you have npm in your system:

npx http-server coco-ui
