I want to add some tiles to an existing tileset in RPG Maker XP. I used Paint Shop Pro 7 (I know it's a bit outdated).
The tileset I used was the Hyrule Castle Town tileset from the Zelda SDK. What I added was some recolored FSA Hyrule Castle tiles. However, when viewed in the editor, they still appear as white space. How can I get these tiles to display so I can place them, as well as define their passage properties?
