Translating win32 to WebAssembly, highly novel and relevant to platform engineering and cloud.
Summary
Theseus, a Rust-based win32/x86 emulator, now compiles binaries to WebAssembly by reusing its binary translation approach with a WebAssembly CPU target. The primary challenge was handling blocking Windows API calls in the browser's single-threaded main thread, which Theseus solves by running emulator threads on web workers while keeping code synchronous for improved debugging and performance. This design abstracts host I/O (mouse, rendering) behind a Host API implemented for SDL and web, enabling direct porting of legacy executables to browsers.
