IronBoy, a highly accurate GameBoy emulator written in Rust, runs WASM
Hey HN! Been working on this emulator on and off for the last couple years, and thought now would be a good time to try and show it off here. As far as unique features... I think this is the only online GameBoy emulator with support for save files? So there's your reason to exist, I guess. The WASM port was something I had in the back of my mind but I just kept putting it off because it seemed like it would've been a pain in the ass to implement, but all in all I think it took less than a week so that was a nice surprise!
In plain words
IronBoy is a GameBoy emulator written in Rust that runs in web browsers via WebAssembly. It allows users to play classic GameBoy games online while preserving and loading save files, a feature the creator claims is unique among online GameBoy emulators. The emulator is designed for retro gaming enthusiasts and developers interested in emulation technology, offering accurate hardware simulation for the original GameBoy platform.
