#RetroBoy is a cycle-accurate #GameBoy #emulator written in Rust. It uses wasm-pack to translate the #Rust #code into #WebAssembly so it can be played on the web. The web frontend then uses Web Audio #API and HTML Canvas for audio and graphics. It also leverages the browser's local storage to persist cartridge RAM data for battery-backed MBC cartridges https://github.com/smparsons/retroboy
