NDDEMO[1] (short for "Nintendo Developer Demo"; referred to in-game as Welcome to GameCube World!!) is a 2001 interactive tech demo[2] included in the software development kit for the Nintendo GameCube, created to show developers the system's graphical capabilities.

In the demo, the player controls a red arrow that can navigate various rooms in Peach's Castle from Super Mario 64, with each room demonstrating a different graphical effect, such as bump mapping, anti-aliasing, or environment mapping.


#0 Peach Castle - ENTRANCE[edit]

The main hub area featuring 6 doors, 5 of which lead to other rooms. This room features several animated objects throughout, as well as a map of the Castle at the center of the bottom floor.

#1 Huge Texture - DOME[edit]

A small room with floral and mountain-themed murals on the walls. The floor has a Super Star with a flower in the background, which is revealed to be made of a small, repeating texture of three stars when looked at closely.

This room demonstrates the GameCube's support for large, high-resolution textures, as well as mipmapping.

#2 Bump & Shadow - SPIRAL STAIRCASE[edit]

A dimly-lit area with a colored stone pillar and spiral staircase in the center. Once the player reaches the stairs, the red arrow begins bouncing, and the player can lead it to the bottom of the room, where a door leading to the Hangar can be found.

This room features bump mapping, a method of simulating bumps and wrinkles on an object's surface.

#3 Antialiasing - HANGAR[edit]

An indoor hangar with a biplane. Next to it, the player can find a metal Warp Pipe which leads to the Cave. This room demonstrates the GameCube's anti-aliasing functionality, most prominently with the wire-mesh fences.

#4 Local Lighting - CAVE[edit]

A cave featuring a wooden bridge which leads to a Goomba statue, with some bulbs and colored projector lights illuminating the path. This room demonstrates the GameCube's real-time lighting capabilities, with lights and casted shadows updating to reflect their source's position.

Entering the green Warp Pipe at the beginning of the area takes the player to the top floor of the Entrance.

#5 Projection Texture - CINEMA THEATER[edit]

A small screening room where a short looping video (featuring prototype GameCube consoles of various colors), along with a blue star and pink heart, are projected and moved around the room.

This area demonstrates projected textures, which can be animated, overlayed on top of each other, and projected over many objects in real-time.

#6 Environment Mapping - METAL MARIO !![edit]

A small room featuring a large Metal Mario statue that reflects its surroundings, meant to demonstrate environment mapping.

#7 Maximum POLYGONS - How Many COINS?[edit]

A white room with a ? Block at the center. Pressing A Button while underneath will release a large amount of differently-colored Coins and stars. This room demonstrates the large amount of polygons, models, and objects that the GameCube can process and display at once.

The player can use +Control Pad to adjust how many coins appear when the ? Block is hit, up to 1024 at once; +Control Pad up and +Control Pad down increase and decrease the amount by 20, while +Control Pad right and +Control Pad left increase and decrease by 1. The exact amount can be viewed by enabling "System Info" in the pause menu.

Pressing B Button exits the room; as such, camera control mode is activated by pressing X Button instead.


Camera Control Mode[edit]

By pressing B Button, the player can freely control the camera's angle and position. Control Stick adjusts the camera's position, and C Stick controls its angle; pressing L Button or R Button raises and lowers it respectively. Pressing B Button again returns to the arrow.

Wireframe Mode[edit]

Pressing Y Button enables a wireframe display mode, hiding textures and making the edges of polygons more distinct.

The wireframe mode causes reduced performance (as shown on the resource usage meter), most noticeably in the Entrance and How Many Coins? rooms.

Pause Menu[edit]

Pressing START/PAUSE Button opens the pause menu; here, the player can toggle mipmap levels, the GameCube's output resolution, system debug information, a resource usage meter, gamma levels, background music, and sound effects.

The player may also access the main menu, where two modes are selectable: Normal Demo (default; the player controls the red arrow to explore the castle), or Auto Demo (the camera is controlled automatically, cycling through the different rooms). Additionally, individual rooms can be selected for either mode.


When the player reaches a door, the arrow will "knock" on the door until the corresponding room is finished loading. To reduce load times, the room the player is meant to enter next is loaded ahead of time, indicated by the star on the door being yellow instead of stone-gray.

  • R Button - Reset the camera behind the player, lower the camera in camera control mode, fast-forward in Auto Demo
  • START/PAUSE Button - Enter pause menu
  • Control Stick - Move the arrow, adjust the camera's position in camera control mode
  • C Stick - Rotate the camera around the player, adjust the camera's angle in camera control mode
  • +Control Pad - Adjust how many coins appear when the ? Block is hit in How Many Coins?
