That recording is translated into C - the original instructions, one for one, with the exact cycle timing of the emulated machine.  The C is compiled to WebAssembly, together with models of the hardware the demo talks to: the timer , the VGA card and the Sound Blaster .  The result is checked against the emulator event for event: every interrupt, port access and frame at the same moment of emulated time.   The demos' own loaders, music players and effects all run as they did in 1992 and 1993; only the hardware is modelled. The demos ran on VGA at 70 Hz , so they look smoothest on a display running at 70 Hz, or at 140 Hz or higher.
