  Retro Boy is a simple Game Boy emulator written in Rust and compiled to WebAssembly, allowing it to run directly in a web browser. It features a basic but functional graphical user interface and supports sound, offering a playable experience for a selection of ROMs. While not aiming for perfect accuracy or advanced features, it focuses on clean code and serves as a learning project showcasing Rust and WebAssembly for emulation.

  Stephen Parsons has developed Retro Boy, a Game Boy emulator meticulously crafted using the Rust programming language. This emulator isn't just confined to a desktop environment; it's been ingeniously designed to run directly within a web browser, leveraging the power of WebAssembly. This allows users to experience the nostalgia of classic Game Boy titles without the need for downloads or installations. The project's core is written in idiomatic Rust, taking advantage of the language's performance characteristics and memory safety features. This Rust core is then compiled to WebAssembly, a binary instruction format designed for web browsers, allowing for near-native execution speed. The user interface, which handles user interactions and presents the game's visuals, is implemented using standard web technologies like HTML, CSS, and JavaScript. These technologies interact with the WebAssembly module, sending user inputs and receiving graphical output for display. Retro Boy emulates the original Game Boy hardware, including the CPU, memory, graphics processing unit (GPU), and sound chip. This allows for accurate reproduction of the Game Boy's visual and auditory experience, offering a faithful recreation of classic gameplay. The project's GitHub repository provides comprehensive documentation, including instructions on building the emulator from source and running it locally. This empowers users to explore the inner workings of the emulator and potentially contribute to its development. While the emulator currently supports a subset of Game Boy ROMs, showcasing its functionality, the project remains under active development with plans for further enhancements and improvements to compatibility. The project demonstrates a practical application of WebAssembly for performance-intensive tasks like emulation, bringing the classic gaming experience to a wider audience through the accessibility of the web.
