The author implements WATaBoy, a Game Boy emulator that compiles Game Boy CPU instructions to WebAssembly (WASM) at runtime using Just-In-Time (JIT) compilation. Benchmarks demonstrate that this approach outperforms traditional native interpreters in terms of execution speed within the browser environment.
Background
WebAssembly has become a standard for high-performance web applications, often used to port complex software like emulators to the browser. JIT compilation is a technique where code is compiled during execution to optimize performance dynamically.
