He cheated and used a PC gfx card
That's not true, the card I used was designed by Phase5 specifically for the Amiga A1200 and doesn't fit in any PC I've seen :-P
Even the chip that's on it supports proper big-endian 32-bit ARGB pixel modes, none of this horrid 32-bit ABGR filth.
However, it is a cheat because it's not running on the 68K, nor on OS3.x and is totally dependent on the graphics card to do the polygon rasterizing.
