# Z-Code Story Files

Place your Z-machine story files here. The Zork Narrator engine looks for
`zork1.bin` by default. This can be overridden with the `ZORK_STORY_FILE`
environment variable.

## Obtaining Zork I

The Zork I story file (`zork1.bin`, also distributed as `ZORK1.DAT` or as a
`.z3` or `.z5` file) is copyrighted by Infocom / Activision. It is not
included in this repository.

You can obtain a legal copy via:

- The **Zork Trilogy** on GOG.com or Steam (includes the original data files).
- The [Internet Archive](https://archive.org/details/Zork_I_The_Great_Underground_Empire_1980_Infocom)
  hosts a playable version in-browser; the original data files are part of some
  archived distributions listed under the Infocom catalogue.

Once you have the file, rename it to `zork1.bin` and place it in this folder,
or set `ZORK_STORY_FILE=./path/to/your/file` in your `.env`.

## Supported Formats

The `ifvms` interpreter accepts:
- `.z3`, `.z4`, `.z5`, `.z8` — raw Z-machine story files
- `.zblorb` — Blorb-wrapped story files (may include sound resources)
- Any file with the correct Z-machine header (the extension is ignored)

Zork I is a Z-machine version 3 (`.z3`) game.
