View source for Z-code games in uncommon formats

Most post-[[Infocom]] [[Z-code]] games are created for either version 5 or version 8 of the [[Z-machine]], and as such, the names of their [[story file]]s conventionally end in <tt>.z5</tt> or <tt>.z8</tt> respectively.

However, there are [[Z-machine versions|other versions of the Z-machine]] that are also available, although rarely used. This page lists some of those games.

==Z1 Games==
(Used by Infocom only for very early builds of [[Zork I]].)
* ''[[Fade to Black]]'' ([[Jake Wildstrom]]; 2004). [[Speed-IF Century]].

==Z2 Games==
(Used by Infocom only for some early builds of [[Zork I]] and [[Zork II|II]].)
* ''[[Little Green Robbing Hood]]'' ([[Jake Wildstrom]]; 21-Jan-2006). [[Speed-IF Gruff]]

==Z3 Games==
The most common version used for Infocom games.

While uncommon in the first decades post-Infocom, in the late 2010s there was a revival of interest in the Z3 format by the retro-machines community, leading to e.g. bugfixes in [[Inform 6]]'s Z3 support in 6.34 (2020). Since then, occasional new Z3 releases are not uncommon; this is by no means a complete list.
* ''[[Catseye]]'' ([[Dave Bernazzani]]; 2004).
* ''[[Endgame (by Denton)|Endgame]]'' ([[Samuel T. Denton]]; 2004). [[C32 Contest]].
* ''[[Moonglow]]'' ([[Dave Bernazzani]]; 2004).
* ''[[Turning Point]]'' ([[Robert Rafgon]]; 2004). [[C32 Contest]].
* ''[[Zombies!]]'' ([[Chris Cenotti]]; 2004). [[C32 Contest]].

==Z4 Games==
Used by Infocom for a few games ([[A Mind Forever Voyaging]], [[Trinity]], [[Bureaucracy]], [[Nord and Bert Couldn't Make Head or Tail of It|Nord and Bert]]).
* ''[[Words Get Twisted Round and Tumble Down]]'' ([[Gunther Schmidl]]; 2000). [[2000 IF Art Show]].

==Z6 Games==
Used by Infocom for its graphical games ([[Shogun]], [[Zork Zero]], [[Arthur: The Quest for Excalibur|Arthur]], [[Journey]]).
