It is important to distinguish between a true "emulator" and a "simulator." A full operating system emulator, like the open-source project v86, translates actual x86 machine code into WebAssembly (WASM) in real-time, allowing a real copy of Windows XP to boot. However, many popular browser-based experiences, such as Win32.run, are actually high-fidelity simulators built entirely with web frameworks (like Svelte, JavaScript, and CSS). These provide a similar look and functionality—including a file system, Paint, and Minesweeper—without needing the actual Windows kernel to run.

: VirtualXP uses a modified version of Halfix, which translates x86 machine code into WebAssembly in real time to run the OS.
