For a system as demanding as Windows XP, this requires the emulation of a Pentium-class processor, significant amounts of RAM, a VGA-compatible video card, and IDE controllers for disk access. Because JavaScript was not originally designed for the high-speed processing required for CPU emulation, the project utilizes modern browser optimizations and WebAssembly to achieve speeds that make Windows XP functional for the average user.
