The classic distribution model for ZZT content has been a manual-copying model, with users having to fetch world files or tools from a website, deploy the content on their own hard disk, and run all content locally.

ZZT Ultra has a more advanced hosting model. The system not only provides downloadable content, but also establishes a web-hosting environment for anyone to deploy server-side.

ZZT Ultra Distribution Package

This ZIP file contains the latest ZZT Ultra distribution package.


This is the README containing deployment instructions. It is also embedded within the ZIP file package.

The instructions assume that you are a competent webmaster.

If you wish to deploy ZZT Ultra locally on your own computer, this is also possible, but you will not be able to use any content-hosting features. When ZZT Ultra is deployed locally, it remains "sandboxed" to the local configuration only. This is the "classic" way ZZT has been used: local and non-netted.


This is the change log for ZZT Ultra progress as a whole, including the engine, the website, and various support tools.

Other Tools

ZZT Imager is a convenience tool for converting images to ZZT metadata. The idea is that any bitmap image can be loaded into the tool and translated into either a ZZT Ultra GUI or a ZZT Ultra board design. This tool also creates content compatible with the legacy ZZT and Super ZZT editors.

ZZT Sound Plus is a tool in the concept stages. The idea is that any digital audio file can be loaded into the tool and translated into one or more equivalent "#PLAY" strings. The user will have the ability to configure the destination parameters, including number of channels, tempo and minimum duration, and other factors.
