Hardcore.

The Microprose games have a means of verifying their graphics hardware by checking the contents of the span-drawing RAM. This meant that there was a software implementation of the triangle rasteriser I could use as a reference

That's awesome.

The best case I found is that Glide always renders a test triangle and then reads back the framebuffer to ensure that the proper, patented 32bpp-to-15bpp dithering was done exactly to spec. I guess to prevent knockoff Voodoo cards or something.
