## プロジェクトの歴史と使われ方

JNetHack is the Japanese-localized branch of NetHack, packaged for terminal roguelike players who want the classic dungeon game with Japanese text and documentation. Its own README records the localization copyright line beginning in 1993, while the release repository tracks later ports to NetHack 3.6-era bases.

### プロジェクトの歴史

The JNetHack release README describes the project as a Japanization of NetHack and lists Issei Numata, Shigehiro Miyashita, Naoki Hamada, Kentaro Shirakata, and other contributors as copyright holders for the localized portions. That history places JNetHack in the long tradition of NetHack ports and localizations rather than as a separate game engine.

The GitHub release repository focuses on release artifacts and tags. Its tag stream shows NetHack 3.6.0-based JNetHack tags from 2016, NetHack 3.6.1-based tags in 2018, NetHack 3.6.6-based tags in 2020-2022, and a NetHack 3.6.7-based tag in 2023.

### 採用の歴史

Homebrew and MacPorts package JNetHack, which makes it a niche but durable package-manager entry for Japanese NetHack players on Unix-like systems. Its adoption is tied less to broad upstream marketing and more to the persistence of NetHack culture, localization work, and terminal-game packaging.

### 使われ方

Users run JNetHack as a terminal roguelike, with gameplay inherited from NetHack and localized text supplied by the JNetHack patch set. The package is most useful for players who already know the NetHack command vocabulary or want a Japanese-language path into that ecosystem.

### パッケージ好きにとっての重要性

JNetHack is package-nerd interesting because it preserves a language-specific fork of a historically important Unix game. It also illustrates a common packaging pattern for old-school games: a small formula wraps a culturally important patch set, while the upstream cadence follows the base game's release line.

### タイムライン

- 1993: JNetHack localization copyright range begins in the project README.
- 2016: GitHub tags record NetHack 3.6.0-based JNetHack release artifacts.
- 2018: Tags move to NetHack 3.6.1-based release artifacts.
- 2020: Tags move to NetHack 3.6.6-based release artifacts.
- 2023: v3.6.7-0.1 tag appears for the NetHack 3.6.7 base.

### Related projects

- NetHack is the base game and upstream code lineage for JNetHack.
- The jnethack organization also maintains Japanese NetHack documentation projects such as jguidebook.

### ソース

- Homebrew and MacPorts package pages support the package-manager adoption note.
- The GitHub tag pages supply the 3.6-era release sequence.
- The JNetHack README supplies the localization statement, copyright ranges, and contributor list.
