Compile an existing open-source emulator to WebAssembly with Emscripten and run it inside a Web Worker. Share the framebuffer, input queue and audio ring buffer with the main thread through SharedArrayBuffer (which requires cross-origin isolation headers). Split disk images into fixed-size chunks with a manifest and fetch chunks lazily on read so boot is fast. Blit the framebuffer to a canvas each animation frame and wrap it in a period-appropriate bezel.
