Except that no game developer would work this hard on a PC game. It's not like there's a secret switch in CGA that enables this. This is all done with a lot of precisely timed assembly code and register stuffing and it breaks on all but authentic hardware. Everyone else would be writing stuff the way the manuals tell them to.

It's always the case that demo effects can outdo the best the game industry has to offer. Demos don't have to be games at the same time.

This remains my gold standard for 8088/CGA demos, and probably always will. I love bringing the delight and amazement to my friends, in pointing them to this masterwork of yours and your comrades-in-demo, Mr. Leonard.

Emulation is downright impossible at the moment, simply because of just how strictly hardware dependent this demo is. You will need an IBM 5150 computer, an original IBM Color/Graphics Monitor Adapter (which cannot be substituted) and that video card must also have a specific revision of the Motorola MC6845 chip, look on the demo creator's site for more specific information, and (ideally) some sort of composite CRT monitor. This will probably set you back a little over $600, easily much much more. Now, most of that is only so you can get the 256 and 1k+ color hacks working, most everything else works even in emulators decently
