List of Super Mario Maker pre-release and unused content

This is a list of pre-release and unused content for the game Super Mario Maker.

E3 2014
Originally called Mario Maker, this build of the game was first presented at E3 2014 with a demo that the attendees could play with the following differences compared to the final game:
 * There was only one row with fourteen place-able course elements: Brick Blocks, ? Blocks, ? Blocks with Super Mushrooms in them, Ground Blocks, Pipes, Trampolines, Moving Platforms, Coins, Goombas, Koopa Troopas, Hammer Bros., Piranha Plants, and Wings.
 * Ground Blocks were placed in a way similar to Semi-Solid Platforms.
 * In the Super Mario Bros. style, objects had heavier shading, certain objects looked shinier (Coins, Question Blocks, and Brick Blocks), and the background had a grid pattern unlike the final's recreation of the Super Mario Bros. background.
 * There was no sign at the beginning of courses.
 * Coins emitted sparkles when collected.
 * Details that automatically pop up when creating a course weren't in the game yet.
 * Enemies exploded when Mario touched the flagpole.
 * In the demo the timer was set to 999 unlike the final game which can only go up to 500 seconds.
 * The icon for selecting which direction a moving platform should go was circular rather than square.
 * Instead of the clock icon used in the final game, it instead said "Time" over the Time.
 * Trampolines in the Super Mario Bros style had a different sprite that was more true to Super Mario Bros. compared to the final build.
 * Super Mushrooms could not be placed on their own in the demo and were instead in a block automatically.
 * The HUD in the editor looked completely different then in the final game.
 * In the Editor, instead of the rocket ship was a trash can. Also, the Undodog and hand had their original sprites from Mario Paint.
 * There was also an button for placing objects with a hand representing it.
 * Weird Mario had a different sprite which looked more like a stretched out Small Mario instead of having his own unique sprite.
 * In the New Super Mario Bros U theme, the animations were different.
 * The background was flat in the NSMBU theme and none of the objects (clouds, hills, etc.) moved along with the screen.
 * Whenever the player finished a course in the demo, a voice saying Congratulations could be heard, confetti would fall along with some Super Stars, and a few hands would clap for the player. In the Super Mario Bros. style the hands were pixelated, while in the New Super Mario Bros. U style they were smoother.

Game Awards Trailer
During the Game Awards, a trailer for Mario Maker was released. While it was closer to the final game than the E3 2014 build, it was still very different.
 * The object selector's color was red.
 * The object selector had where the number is in the final an object that looked like a ninja star.
 * The Super Mario Bros. 3 style's sign looked different.
 * The Fire Flower's color in the SMB3 style matched the original game's color.
 * The Bill Blaster and Cannon both turned blue in castles and underground even in the Super Mario World style.

Unused costume data
Several unused costumes are referenced in the game's CharaMarioTable.byaml file. None of them have graphics associated with them, however. Note that these names would not have been displayed in-game, as the in-game names are stored in a different file. These text strings are not present in the updated archives in updates 1.01 and above.
