Link to the project: Turbowarp version with Widescreen and Shadows: You can distinguish between World and Level codes by whether they say: “World Title” or “Title”. Then, on the Title Screen of the game, select Load, then select whether you are entering a Level or World code, then paste the code into the textbox and press Enter. You can do this easily by triple clicking it, so it all highlights, then right clicking it and selecting Copy, or pressing Ctrl + C.
To copy a code, you only need to copy the text inside of the box below the Title.
This topic is no longer in use, to post a level, do so on the new topic here: The new topic is being used as this topic has 600 pages of codes, which makes it take a long time to load, this topic is only here as an archive. This is the old forum in which you can find and share level and world codes for Super Mario Maker 4.
