WebAssembly JIT makes a Game Boy emulator faster than native code
A student built WATaBoy, a Game Boy emulator that JIT‑compiles ROM instructions into WebAssembly at runtime. In browsers, the generated Wasm beats a native C interpreter, flipping the usual performance expectation. The result shows WebAssembly’s JIT can outperform handcrafted native emulation for CPU‑bound workloads.
