DOOM runs (slowly) in a IBM PC-Compatible CSS Sheet

Just when you thought we’d run out of things to port DOOM to, here comes [Ahmed Amer] with his CSS-DOS, a massive 300 MB CSS style sheet, that runs not just DOS, but Windows 1.0 and, of course, DOOM . The CSS sheet isn’t holding a DOOM port this time, though — it’s holding a full IBM PC compatible, with a simulated 8086, 640 kB of RAM, floppy and VGA controllers. We did mention it was 300 MB, right?
