Hey, i have no idea if there are LoZ: ALttP guy's here, but here is a little program i wrote.
Due to the lack of Hyrule Magic in using all 4 staircases/doors for each room, i wrote a little program that does that. You have a text file in which you can write your rooms and then execute it after editing with Hyrule Magic to add the rooms.
Look at the readme file for explanations.
Big thanks to MathOnNapkins for his documents and personal help :-).
The program is called "Room Header Expander"http://www.le-softworks.com/RHE.zip
If someone find it useful, please give me a little feedback :-).
