The Nintendo DS (ニンテンドーDS
?
) (sometimes abbreviated NDS or DS, also

as iQue DS in China) is a handheld game console developed and manufactured
by Nintendo and was released in 2004. The console features a clamshell
design, with two LCD screens inside - one of which is a touch sensitive screen.
The Nintendo DS also features a built-in microphone and supports wireless
IEEE 802.11 (WiFi) standards,
[6]
allowing players to interact with each other
within short range (30–100 feet, depending on conditions) or online with the
Nintendo Wi-Fi Connection service. The system's code-name was "Project
Nitro".
The letters "DS" in the name are meant to stand for Developers' System,
which refers to the features of the handheld designed to encourage innovative
gameplay ideas among developers. It can also stand for Dual Screen.
[7]

On March 2, 2006, Nintendo released the Nintendo DS Lite, a redesign of the
Nintendo DS in Japan. It was later released in North America, Europe and
Australia in June 2006. The DS Lite is a slimmer and lighter version of the
Nintendo DS and has brighter screens.

Input and output


The Nintendo DS stylus used for games played on the touch-screen
The lower display of the Nintendo DS is overlaid with a pressure-sensitive
touch screen, designed to accept input from the included stylus, the user's
fingers, or the "thumb stylus": a curved plastic rectangle attached to the
optional wrist strap. The touch screen allows players to interact with in-game
elements more directly than by pressing buttons; for example, in Trauma

Center: Under the Knife, the stylus may be used as a scalpel to cut an incision
in a diseased patient, or in the included chatting software, PictoChat, the
stylus is used to write messages or draw.
Traditional controls are located on either side of the touch screen. To the left
is a D-pad, with a narrow Power button above it, and to the right are the A, B,
X, and Y buttons, with narrow Select and Start buttons above them. Shoulder
buttons L and R are located on the upper corners of the lower half of the
system. The overall button layout is similar to the controller of the Super
Nintendo Entertainment System.
The Nintendo DS features stereo speakers providing virtual surround sound
(depending on the software) located on either side of the upper display screen.
This is a first for a Nintendo handheld, as the Game Boy line of systems has
only supported stereo sound through the use of headphones or external
speakers.
A built-in microphone is located below the left side of the bottom screen. It
has been used for a variety of purposes, including speech recognition
(Nintendogs), chatting during gameplay (Metroid Prime Hunters), and
minigames that require the player to blow or shout into the microphone (Feel
the Magic: XY/XX, Mario Kart DS etc).

Specs
 Mass: 275 grams (9.7 ounces).
 Physical size: 148.7 x 84.7 x 28.9 mm (5.85 x 3.33 x 1.13 inches.
 Screens: Two separate 3-inch TFT LCD, resolution of 256 x 192 pixels,
dimensions of 62 x 46 mm and 77 mm diagonal, and a dot pitch of 0.24
mm. Note The gap between the screens is approximately 21mm,
equivalent to about 92 "hidden" lines. The lowermost display of the
Nintendo DS is overlaid with a resistive touch screen, which registers
pressure from one point on the screen at a time, averaging multiple
points of contact if necessary.

 CPUs: Two ARM processors, an ARM946E-S main CPU and
ARM7TDMI co-processor at clock speeds of 67 MHz and 33 MHz
respectively, with 4 MB of main memory which requires 1.65 volts.
The system's 3D hardware performs transform and lighting, texture-
coordinate transformation, texture mapping, alpha blending, anti-aliasing, cel
shading and z-buffering. However, it uses Point (nearest neighbor) texture
filtering, leading to some titles having a blocky appearance. The system is
theoretically capable of rendering 120,000 triangles per second at 30 frames
per second. Unlike most 3D hardware, it has a limit on the number of
triangles it can render as part of a single scene; this limit is somewhere in the
region of 4000 triangles. The 3D hardware is designed to render to a single
screen at a time, so rendering 3D to both screens is difficult and decreases
performance significantly. However, games such as Viewtiful Joe: Double
Trouble run 3D on both screens at once in gameplay, and still keep good
performance and quality.
The system has two 2D engines, one per screen. These are similar to (but more
powerful than) the Game Boy Advance's 2D engine.
Games use a proprietary solid state ROM "Game Card" format resembling
the memory cards used in other portable electronic devices such as digital
cameras. It currently supports cards up to 1 gigabit
[8]
in size (used in Final
Fantasy III and Rune Factory for instance). The cards usually also have a
small amount of flash memory or an EEPROM to save user data, for example
progress in a game or high scores. The game cards are 33.0 × 35.0 × 3.8 mm,
and weigh around 3.5 grams (1/8 ounces).
The unit features wireless networking capabilities for multiplayer games or
chat using Wi-Fi. Wireless multiplayer games, including the PictoChat
capability and wireless game download use a proprietary protocol on top of
IEEE 802.11, commonly known as Ni-Fi. Many newer games can use the

Nintendo Wi-Fi Connection to communicate with other systems anywhere in
the world, using a compatible
[9]
Wi-Fi router or the Nintendo Wi-Fi USB
Connector with the usual IP-based protocols, besides offering direct DS-to-DS
wireless communications using the older system.
[edit]
Firmware
Nintendo's own custom firmware boots the system (first requiring the player
to read health information): from here, the user chooses to run a Nintendo DS
or Game Boy Advance game, use PictoChat, or search for downloadable
games. The latter is an adaptation of the Game Boy Advance's popular "single
cartridge multiplayer" feature, adapted to support the system's Wi-Fi link
capabilities (players without the game search for content, while players with
the game broadcast it. The game host is able to set the rules of the game).
In November 2004, Nintendo announced that there could be some sort of
"download kiosk" that would transmit a signal for a Nintendo DS in the area
to pick up, and download a demo of a game (Just like the "Download Play"
feature that it in fact, uses). As of 2006, there are now download kiosks placed
in select EB Games, GameStop, Game Crazy, and Target stores.
The PictoChat program, which is permanently stored on the unit, allows users
to communicate with other Nintendo DS users within range over the wireless
network by text, handwriting, or drawings, using the DS's touch screen and
