The I of the Dragon — fan tools (localization + HD)

Reverse-engineering and localization tooling for The I of the Dragon (Topware / Primal Software).

This repository tracks only our own tools and documentation. It does not contain the game, its assets, or any cracked distribution — those are regenerated/produced locally from a legit copy.

Layout

tools/            Python tooling (unpack, repack, preprocess, font patch, decoders)
docs/             DEVLOG, format specs, patch notes

Working data (not tracked): original/, png/, report/, patch/, crack/.

Current localization status

The complete tutorial translation and Chinese font fixes were accepted in game by the user on 2026-09-20. All 57 tutorial display literals are translated using 42 mappings. Tooltip wrapping, option-title centering, intro alignment, and the Chinese full-stop baseline are fixed. The latest targeted regression run passes 39 tests; tutorial event logic remains byte-identical outside display strings.

See 教程汉化：构建、验证与恢复 for reproducible commands, accepted behavior, and the remaining project queue.
