Crimsonland (2003) is a top-down shooter that shipped as a stripped DirectX 8 binary with zero symbols. I decompiled it with Ghidra, validated behavior with WinDbg and Frida, and rewrote it from scratch in Python/Raylib — 46,800 lines matching the original behavior faithfully. The write-up covers static and runtime analysis, reverse engineering custom asset formats, and the full rewrite process. Code is on GitHub and it's playable now via uvx crimsonland@latest

Very fun use of an agentic loop :). Do you have any info/data about how many tokens this ended up consuming in that time?

Wow! What a blast from the past. I remember 13yo spending day after day on this game despite being an avid crpg player those days.

Going to give this a spin after work. Thanks for the work and the writeup!

.....python? Why a slow scripting lang?
