This is a question about RPG Maker, but I've been trying to add a Nexus connection to Neon City. So I add a simple image of a cactus to one of the game's charsets, then I open it up on RPG Maker and the entire thing is just... black. Then I try actually going to the Neon City, and the game crashes, saying "unsupported PNG image" Does anyone know why editing that charset makes it "unsupported", and how I can fix it?
