Lemmings, or how clever tricks make platforms more different than they seem
The other day I read this in-depth article on font usage in early DOS games by VileR. Since some of the fonts were apparently stored not as 1-bit bitmaps, but as multiple bits per pixel, I was wondering when the … Continue reading

The DOS SDK
A thing I have been working on, on and off, for many years now, is a set of headers and helper routines for programming DOS machines directly on the hardware in assembly and C. As you may recall, my earliest … Continue reading
