This package implements an API for the core behaviors of a Z-Machine interpreter
It aims to support Z-Machine games of versions 1, 2, 3, 4, 5, 7, and 8 (i.e. all but version 6) as described in the Z-Machine Standards Document version 1.1 https://inform-fiction.org/zmachine/standards/z1point1/index.html
A full interpreter would add screen rendering, keyboard input, sound, and file access components to this core to produce a playable interpreter. See this link from the future as an example: <future link goes here>
This package is a hobby project for me, so I shouldn't promise too much regarding bug fixes and feature requests, but in general I'd love to hear about what is and is not working for you
