The Wizardry 7 editor I had in mind can be found by choosing item 4b "Another character/item editor", at:
http://www.angelfire.com/games/stg45/ . It's called "dsedit". W7edit is good too, but I liked dsedit better.
The one mentioned a few posts above looks even better, but alas! seems to require payment. What I like about dsedit, is that it lets you view ALL the items written into the game, even some that I have NEVER encountered in my many, many play-throughs.
Enjoy the hack!
