Solarus and Solarus Quest Editor don’t provide any Zelda graphics, sounds or names. Only some quests do.
If you want to use graphics and sounds of The Legend of Zelda: A Link to the Past, you might be interested in our resource Zelda ALTTP pack, below. This is still a work in progress, but it is based on what we used for Mystery of Solarus DX. Please keep in mind that assets from Zelda are obviously copyrighted and cannot be used for a commercial game.
Some people are working on creating resource packs for Solarus. The forum has a section for resource packs, where users can share their work.
