From the README

A Game Boy and Game Boy Color emulator written in Rust, running in the browser through WebAssembly.

▶ Play it in your browser: drop in a .gb or .gbc file (free, legal homebrew games are on Homebrew Hub, e.g. Tobu Tobu Girl, or its Color edition, Tobu Tobu Girl Deluxe).

Status: plays original Game Boy (DMG) and Game Boy Color games with sound, battery saves, save states, rewind and a debugger, in the browser or headless. Games that support the Color run in color; original games run as on the original Game Boy, or in color on a Game Boy Color with the palette of your choice.
