ZZT 4.1 is a hex edit of ZZT 3.2 created by WiL for widespread use. Unfortunately, the publicly available version of ZZT 4.1 is an unfinished build:
4.1 is almost certainly bad. The version of zzt 4.1 that was uploaded was from the wrong folder, wrong exe. An oversight I realized too late.
This version of the executable was released on May 12th, 2012.
While there is nothing stopping this ZZT hex edit from running on pre-80386 machines - including Zeta - at face value, it has been compressed with UPX without enabling the –8086 flag; as such, to run it on an 8086/80186/80286-class machine or Zeta, it must be decompressed first with upx -d.
The final release in the ZZT 4.x series
Released during the Glorious Trainwrecks' Glorious Weekend of ZZT Blitzkrieg-o-thon 5/11/2012.
* ZZT's 20k board limit has been increased to 65k.
* ZZT's bottom-row placement bug has been fixed.
* ZZT is now 39k.
* untitled.zzt, temp.brd, and saved.sav will no longer be the default. Now by default you must put in a name of your own. This means no more angst over accidentally saving over your last board, saved game, or ZZT project.
* 255 objects per board, 255 boards per zzt world.
* Removed most in-game messages and sound effects. Kept the item pick-up messages and the invisible wall sound and message.
* The game no longer crashes if your cursor accidentally wanders off the board when using f4 in the editor. (If you continue typing off into oblivion, though, it will still crash)
Examining the actual changes made seems to confirm WiL's words - most of the documented changes are not present in the binary.
Y < 25 requirement from OopExecute's #PUT handling is replaced with Y < 26, fixing the #PUT bottom row bug (offset 0xC9E1).| Description | Location | Original string | Modified string |
