WasmBoy is a Game Boy / Game Boy Color Emulator Library, 🎮written for WebAssembly using AssemblyScript. 🚀Shell/Debugger in Preact. ⚛️

WasmBoy uses Wasm for it's emulation core, which runs all of the heavy logic of emulating the GameBoy. This is all placed within a web worker, for parallel computation, and leaving the main thread to respond to user input.

WasmBoy directly acheived up to 60% speedup compared to the TypeScript compiled JavaScript implementation on low-end devices by using WebAssembly. Bringing emulation to low-end devices on the web. This was documented in this benchmark article.
