Super Mario Maker for Nintendo 3DS

Super Mario Maker for Nintendo 3DS is a Nintendo 3DS port of the 2015 Wii U title Super Mario Maker. Despite being a Nintendo 3DS title, the game does not support stereoscopic 3D. It was released worldwide in December 2016, roughly 15 months after the original.

Changes and new features
The game includes almost everything from the original Wii U release, with the exception of the Costume Mario and Big Mario forms and searching for courses by code. It is also possible to play stages from the Wii U version, though not every stage is compatible with the 3DS version due to version differences, such as the removal of Mystery Mushrooms and Big Mushrooms from the 3DS version.

Exclusive to Super Mario Maker for Nintendo 3DS, the game includes 100 new courses designed by Nintendo pre-installed. The courses also include medal objectives, in which the player must fulfill certain criteria, such as collecting every coin in the level, to earn a medal. Players can also send unfinished courses to other players, by way of Local Play, and they can team up, or collaborate, on stages. Stages made in this way have a special icon marked next to it. The editing mode of the game also includes Yamamura's Lessons, an interactive tutorial guided by Mary O. and Yamamura.

The Super Mario Challenge mode features a map that has 18 worlds. The number of levels start at four (Worlds 1-7, 10-12, 14-16), increases to six (Worlds 8 and 13), then increase to eight (Worlds 17 and 18), and finally to twelve (hidden World 19) with the color of the world map background gradually changing as well (with the exception of 19 exclusive to Coursebot).

Differences between versions

 * The following elements have been removed from the Nintendo 3DS version:
 * Mystery Mushrooms; the Weird Mushroom replaces the Mystery Mushroom as the game theme-specific power-up in the Super Mario Bros. game theme.
 * Big Mushrooms.
 * Cat paws and its other hands.
 * The Gnat Attack minigame.
 * Course IDs and courses with the Mystery Mushroom and/or Big Mushroom items (although the player can download Wii U courses from the internet and participate in the 100 Mario Challenge).
 * Additionally, the Super Mario Maker Bookmark portal site has been removed from the Nintendo 3DS version.
 * Checkpoint Flags, Skewers, and Keys are now standalone course elements, meaning they do not need to be created by shaking an arrow sign, a Thwomp, or a P Switch, respectively.
 * The following elements are now available from the start:
 * The Super Mario Bros. 3 and Super Mario World game styles.
 * The Underwater, Airship, Ghost House, and Castle course themes.
 * Mario's trail display, the timer and autoscroll settings, the sound effects menu, and the ability to create sub-areas.
 * Donut Blocks, Fire Flowers, 1-Up Mushrooms, Lifts, Cheep Cheeps, Bloopers, Spike Traps, Semi-Solid Platforms, Warp Doors (but not P Warp Doors or Key Doors), Checkpoint Flags, the game style specific power-ups (Weird Mushrooms, Super Leaves, Cape Feathers, and Propeller Mushrooms), Super Stars, Bill Blasters, Boos (but not Boo Buddies), Dry Bones, Fire Bars, Burners, Hammer Bros., Bowser (but not Bowser Jr.), and Tracks—however, Coins, Trampolines, and Piranha Plants can no longer be turned into Pink Coins, Sideways Trampolines, and Fire Piranha Plants, respectively, until certain points.
 * Shaking the following elements does not give them alternate forms until the player meets certain conditions:
 * Coins cannot be turned into Pink Coins until all of the secret World 19 courses have been cleared.
 * Trampolines cannot be turned into Sideways Trampolines until World 9 of Super Mario Challenge has been cleared.
 * Piranha Plants cannot be turned into Fire Piranha Plants until World 4 of Super Mario Challenge has been cleared.
 * Warp Doors cannot be turned into P Warp Doors or Key Doors until Worlds 12 and 18, respectively, of Super Mario Challenge have been cleared.
 * Boos cannot be turned into Boo Buddies until World 9 of Super Mario Challenge has been cleared.
 * Bowser cannot be turned into Bowser Jr. until all of the secret World 19 courses have been cleared.
 * Rocky Wrenches cannot be turned into Monty Moles until World 6 of Super Mario Challenge has been cleared.
 * Buzzy Beetles cannot be turned into Buzzy Beetle Shells until World 15 of Super Mario Challenge has been cleared.
 * Spinies cannot be turned into Spiny Shells until World 16 of Super Mario Challenge has been cleared.
 * Grinders cannot be turned into Bumpers until World 16 of Super Mario Challenge has been cleared.
 * Koopa Clown Cars cannot be turned into Fire Koopa Clown Cars until World 18 of Super Mario Challenge has been cleared.
 * The Nintendo 3DS version has seven item interface columns with nine items each, as opposed to its Wii U predecessor, which has five columns with twelve items each. Also, there is not a crown column, and all items completely fill each column.
 * The Nintendo 3DS version supports the ability for different players to collaborate on courses together via Local Play.
 * Players can share their courses with other players via Local Play or StreetPass, rather than uploading them.
 * There are fewer buttons when searching online courses.
 * 10 Mario Challenge has been replaced with Super Mario Challenge, which consists of 100 courses designed by Nintendo in 18 different worlds.
 * Half of the 60 course elements are unlocked at the start, compared to the Wii U version, which has a set of elements unlocked at a time each day.
 * When placing an object down in the course creator, instead of a distorted voice saying the name of the object, there is simply a small sound that sounds like two sticks tapping each other.
 * It is no longer possible to record custom sound effects.
 * Upon starting the game for the first time, the player no longer needs to play though an unfinished course and a guided tutorial before being able to access the Main Menu. Instead, the player is greeted with an introductory speech from Yamamura and Mary O.

NOTE: This glitch only works on the New Super Mario Bros. U game style.

For this glitch, the player must have a Bowser Jr. and a Koopa Clown Car, regardless of which type it is. When Bowser Jr. takes any form of damage or is far away from Mario, he hides into his shell and starts speeding towards Mario. If he falls into a Koopa Clown Car while inside his shell, his head will be jammed inside, giving somewhat of a headless appearance.

This happens likely due to the Nintendo 3DS port of Super Mario Maker in theory using models for the New Super Mario Bros. U game style rather than sprites as in the Wii U version.

Trivia

 * By way of a glitch or a possible developer oversight, it is possible to spawn Mystery Mushrooms using a Big Magikoopa. Touching the Mystery Mushroom will turn Mario into Small Mario with the same abilities as Super Mario.
 * Through hacking, it is also possible to use Big Mario when playing levels.
