The Reconstruction of Super ZZT is a reverse-engineered recreation of the source code to the last official release of Super ZZT, Super ZZT 2.0.
Super ZZT is a sequel to ZZT, an adventure game created by Tim Sweeney. It was released in October 1991, providing new built-in elements and a large, scrolling playfield.
You can learn more about ZZT and its modern-day community from the README of the Reconstruction of ZZT.
Unlike ZZT, Super ZZT's built-in editor needs to be activated by using the "/E" command-line switch. After doing so, you can press "E" just like in ZZT.
Please note that the popular third-party tool, KevEdit, does not support Super ZZT worlds. Other editors exist which do, like ZAP and ZEdit2.
This release's binary distribution includes the Super ZZT engine executable, SUPERZ.EXE.
The source code includes the source format for SUPERZ.EXE, as well as relevant tools.
Short answer: Sort of.
Long answer: Almost all of the code is byte-accurate. However, Super ZZT utilizes TheDraw's Crunched Screen Image decompression routine for its ANSI art graphical displays. As I did not manage to find clear licensing terms for said routine, UNCRLIB.PAS contains a clean implementation of it. This ensures that the binary produced by this repository is MIT-licensed, even if a non-consequential part of it differs. However, it is possible to replace UNCRLIB.PAS with the original implementation and get a .EXE byte-accurate to Super ZZT 2.0.
This is because the original source code to Super ZZT was lost a long time ago alongside ZZT's.
Yes! There are many ZZT and Super ZZT worlds, utilities, and other documents which have not yet been preserved. If you'd like to share them and see them be adequately catalogued and preserved, please contact me at (kontakt at asie dot pl) - or get in touch with the Museum of ZZT community.

- TOOLS/LZEXE.DOC, TOOLS/LZEXE.EXE:
LZEXE.EXE v0.91 (c) 1989 Fabrice BELLARD
Ce programme fait parti du domaine public (FREEWARE), donc vous pouvez
l'utiliser, le copier et le distribuer sans problème. Et vous pouvez même
en faire un usage commercial, c'est à dire compacter des fichiers EXE que
vous allez vendre. Mais la vente de LZEXE.EXE est interdite.
- DOS-compatible environment (f.e. DOSBox),
- Turbo Pascal 5.5 (if you don't have it, it's officially available for free via Embarcadero's Antique Software website).
- Ensure that TPC.EXE from Turbo Pascal is available on your PATH (f.e.
SET PATH=C:\TP;%PATH%). - From the source code directory, run
BUILD.BAT. - The DIST directory will contain files comprising the release as outlined in the FAQ.
These are variables which are not used at all anywhere in the source code, but are assumed to exist in the stack or data segments, affecting relevant variable offsets and stack checks. They are required for byte-level equivalence, but you are free to remove them and get a functionally equivalent version of the engine - with the exception of some structures, like TStat, which are serialized to disk.
As always, I'd like to thank everyone who has spent the last few years contributing to the rebirth of the small ZZT community.
