| # | Theme | Supporting quotations |
|---|---|---|
| 1 | Homage (and controversy) around Fabien Sanglard’s Game Engine Black Books | “The style, dimensions, and structure of this book are intentionally similar to Fabien’s Game Engine Black Books, as an homage to those masterpieces.” – charlietran “I see in the Keen book's source git commit logs that you reviewed and assisted with proof reading beforehand…” – sasas* |
| 2 | Historical perspective on smooth‑scrolling & Carmack’s breakthrough | “Masters of Doom is a great book on the history of id software, which includes the origins of the development of smooth scrolling by Carmack and Romero, which was groundbreaking at the time on PC.” – evilturnip “The underlying mechanics of Carmack's technique is very similar to the full screen smooth scrolling effect on C64… It is nowadays referred to as DMA delay.” – _the_inflator |
| 3 | Retro engine analysis & source‑code recreation | “To put it briefly, 4th generation and earlier games consoles saved on expensive RAM by not having frame buffers…” – mrob “Great write up. Reminds me of Cosmodoc, which is similar source but analyzes Cosmo’s Cosmic Adventure instead of Commander Keen.” – pan69 |
