Python 3 implementation of a z-machine interpreter, for playing Infocom games. To play a z-machine file:

python -m zmachine [GAME_FILE] [--graphics]

The games will be rendered in a terminal with curses by default. The optional --graphics flag will open the game in a separate window with enhanced graphics rendering. This option has a dependency on the pygame package.

The interpreter supports z-machine versions 3-6. Version 3 is the build for most of the older Infocom games such as the Zork trilogy. Version 4 games include Trinity, AMFV, and Bureaucracy. Version 5 games include Border Zone and Beyond Zork. Version 6 games include Zork Zero, Arthur, and Shogun. Save files are in Quetzal format and should be compatible with the Frotz interpreter.

Version 6 games require graphics rendering and the --graphics flag is enabled by default. The interpreter will recognize a blorb resource that is in the same directory as the game file.

The original Zork trilogy (written by Tim Anderson, Marc Blank, Bruce Daniels, and Dave Lebling) is in the games directory.

The Z-Machine Standards Document, by Graham Nelson, is an indispensable guide for decoding the z-machine instructions.
