	tl;dr: A 214-page full-color technical book dissecting the original 1990 Commander Keen game engine is now available, free as a PDF or in paperback on Amazon, with source code on GitHub. The book details the hardware (80286, EGA, sound cards), game assets, engine internals, and the CGA port, based on three years of reverse-engineering and experimentation.
	HN Discussion: ↓Author used ChatGPT to rewrite and copied content from another author without attribution ~Appreciates the book but suggests adding context comparing PC vs SNES sprite rendering hardware •Recommends similar reverse-engineering resources like Cosmodoc and Masters of Doom ↑Requests expanded coverage of other Apogee/Epic era games ↑Requests additional formats like epub beyond PDF
