I posted this in general but I realized this might be a better place for it.
A large part of TLOZ Expanded will be in dungeons. I will make some modifications to the original map (and I have by adding world bosses and blin camps), but most of the new content will be in dungeons or areas considered "dungeons" by the game.
First off, I need to modify the insides of existing dungeons. The changes to the dungeons will be small, though. Like making Stalfos stronger and thus making them less numerous, while introducing Green Bokoblins to fulfill the role the Stalfos originally did.
But, since the overworld of Hyrule is too small for me to create new areas while also keeping existing ones, I need to make new "dungeons" that function as extensions to the overworld. I am planning on making mini-areas such as the Hebra Peaks, a snowy region in the northwest, as well as the Faron Grove, a jungle in the south.
I am also planning on making an underground world where there is a city entirely populated by fluffy Darknuts, where it is revealed that the ones we fight are a radical group devoted to Ganon called the Pack of Mukade. The rest are just floofs that chill underground and fight amongst themselves.
You also get to buy the Hookshot here.
The underground is also filled to the brim with ReDeads, bug-like monsters that live in hives below the surface and love shiny things. They also eat corpses. Fun, aren't they?
But I'm having difficulties making all this possible. I can create the DMap, sure, but I can't make the area. How exactly do they work? How do I get inside the dungeons to modify the rooms? I can't scroll outside the map where the dungeons would normally be. Is a DMap more of a flag, like something you place on a room to say, "Hey, this is a dungeon."?
How do I make new areas like this? Can I create new rooms? How do y'all do it?
