WATaBoy: JIT-Ing Game Boy Instructions to WASM Beats a Native Interpreter
A developer explores using WebAssembly (Wasm) as a JIT compilation target for a Game Boy emulator to bypass iOS restrictions on native JIT. The project serves as a technical benchmark to compare the performance of Wasm-based JIT against traditional interpreters.
Why it matters
Demonstrates a creative technical workaround for platform-specific software restrictions, highlighting the potential of browser-based engines for high-performance emulation.
Dolphin isn’t on iOS, because you can’t do JIT compilation on iOS. That’s a quick summary of OatmealDome’s blog post “ Why Dolphin Isn’t Coming to the App Store ”. Ever since reading that, I’ve wondered what it would take to get a CPU-bound emulator like Dolphin working on iOS. Do we just... have to wait a few years for iPhone CPUs to get fast enough to run Dolphin with an interpreter?
