Here is my Zelda 1 dungeon Editor, it edits(as the name suggests) Zelda 1 dungeons and it can do a better job than most other dungeon editing utilities out there (apart from the hex editor... well.. that's kinda hard to use :P)

The dungeon editor can edit most of the things you need to make a dungeon work. The only thing it won't edit is the Upper-left-corner map and the starting positions of the normal map and the upper-left-corner map (seriously i never understood how they work :P). The editor assumes you have some knowledge of how the dungeon rooms are setup and hex (there's a little section in the readme about the dungeon rooms, but don't expect me to write up a document for hex)

There may be bugs in the program, see the readme for details.

Download it here (~285kb)

Working on this program in the future is not planned (unless there's mass demands for it, but i doubt that :P)
Enjoy. (updated 10/2/2004)
