Like most zquesters, I don't use screen 80 for caves and buildings; I use a separate map with its own DMap. The DMap type is "cave", and the room types that I've used so far (that work) are "shop", "secret item", and "pay for info." But the rooms "potion shop" and "more bombs" don't work. Is this a limitation of cave DMaps, or did I not set something correctly?
