# th06-headless: deterministic Touhou 6 logic runtime

> th06-headless adapts reconstructed Touhou 6 game logic into a deterministic Linux runtime for replay and learning research. It removes window, audio and frame-pacing requirements, accepts seeded per-tick actions, exports JSONL state, and offers a lockstep observation/action interface. The fork builds on GensokyoClub/th06 and uses the user's original Japanese game data.
