12.3.3. Frotz
Frotz is a Z-Machine interpreter for playing Infocom’s interactive fiction games, and
newer games using the same format. To start a game open a .z1 - .z8 file in the File
Browser. Most modern games are in the .z5 or .z8 format but the older formats used
by Infocom are supported.
Z-Machine games are text based and most depend heavily on typed commands. The
virtual keyboard is used for text entry, both for typing entire lines and for typing single
characters when the game requires single character input.
Sounds, pictures, colour and Unicode are not currently supported, but the interpreter
informs the game of this and almost all games will adapt so that they are still playable.
This port of Frotz attempts to be compliant with the Z-Machine Specification version
1.0.
Some places where you can find Z-Machine games, and information about interactive
fiction:
• The Interactive Fiction Archive, where many free modern works can be down-
loaded: http://www.ifarchive.org/
• The specific folder on the if-archive containing Z-Machine games: http://www.
ifarchive.org/indexes/if-archiveXgamesXzcode.html
• A copy of the Infocom homepage, with information about the classic commercial
Infocom games: http://www.vaxdungeon.com/Infocom/
