Metal Mutant: a browser engine reconstructed from the DOS game

Metal Mutant in the browser reimplements the 1991 DOS game's engine in JavaScript and runs the player's original scripts, graphics and sounds. It rewrites the interpreter, object scheduler, renderer, interrupts and PC-speaker audio routine by routine; the author reports frame-by-frame memory and screen comparisons with the original.
