This patch gives you maximum health, torches, gems, ammo and a key of every color in every savegame.

Oh yeah, some of those files are "protected" against editing (in the internal editor)

Load the desired .ZZT file into your hex editor.
Search for SECRET and change the  (06 hex) to a NULL (00 hex).

Conversely, adding a  before the SECRET in your own .ZZT files will make them uneditable. (Information from Cheat Machine)
