# 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/`.

## Tooling

| script | purpose |
|---|---|
| `tools/res_unpack.py`      | extract a `.res` archive (index + raw blobs, 16-byte aligned) |
| `tools/res_repack.py`      | rebuild a `.res` byte-identically from a directory |
| `tools/preprocess.py`      | convert textures to PNG + build classification report |
| `tools/make_plan.py`       | build an HD upscale plan from the report |
| `tools/decode_dat.py`      | decode/encode the XOR-obfuscated `Fonts.dat` / `*Description.dat` |
| `tools/fontparse.py`       | parse `Fonts.dat` into font blocks and glyph rects |
| `tools/add_section.py`     | add an executable section to the game PE |
| `tools/apply_cjk.py`       | apply the double-byte font-rendering patch |
| `tools/xrefs.py`           | find call/jmp xrefs in the game executable |

See `docs/` for the reverse-engineered formats and addresses.

## Legal

No game data is distributed here. Patches are produced by the user against their own copy.
