Cleanroom reverse engineering of Zanac AI for MSX 1 (by Compile, 1986)

Today, July 25th, is the 40th anniversary of the release of Zanac AI, by Compile in 1986 for the MSX 1 system in Japan.

As a kid, I marveled about the complexity, fluidity, challenge, and overall perfection of the first version of Zanac.

Since then I always wanted to understand the genius programming and game crafting skills from the early Compile staff.

Today, helped by agentic AI, I'm happy to share with the community a full documentation effort and cleanroom disassembly of this specific version:
