Nintendo is a ship’s company whose very name is synonymous with picture play . Chances are that you have played on , or at least see , one of the three generation of home picture game system the company has created , not to mention the enormously democratic hand - nurse game system , theGameboy . The current system , theNintendo 64(N64 ) , was a technical tour de force when it was introduced , and still compares admirably to other console on the market .
As you read through the next few pages , you will learn how the N64 was develop , what ’s inside the boxwood , how the comptroller works and how it all works together . You will also memorise about the game pickup and how they take issue from compact disc - base game , all in this edition ofHowStuffWorks .
History
Just asAtariushered in the sunup of the household TV biz , Nintendo is largely considered to be the company that revolutionized the industry with the introduction of theNintendo Entertainment System(NES ) in 1985 . An 8 - bit arrangement found on the 6502 processor and some custom chips , the NES come together withSuper Mario Brothers ; this inclusion of an accurate home interlingual rendition of one of the most pop arcade games at the time turn out to be pure genius . sale of the NES were phenomenal . This established Nintendo as the dominant place television game maker until the late ' 90s , when it was eclipsed by the rival SonyPlayStation .
In 1989 , Nintendo introduced a new 16 - moment system dubbed theSuper Nintendo Entertainment System(SNES ) . Within a couple of year , rivals had introduce 32 - bit system that eclipse the capabilities of the SNES . So , Nintendo announced an agreement withSilicon Graphics Inc.(SGI ) to develop a young 64 - bit video game system , code - namedProject Reality . Although SGI had never designed video secret plan hardware before , the ship’s company was regarded as one of the loss leader in computer graphics applied science .
After several years of development , the system of rules was finally free in 1996 as the Nintendo 64 . But the holdup and famine of game during the first yr of availability gave the advantage to Sony , who had released the PlayStation over a year earlier . Nintendo is facing the same post again with the SonyPlayStation 2debuting in 2000 , while Nintendo’sGamecubeis not due until Fall 2001 .

allow ’s take a look at the components inside an N64 , and what their capability are . [ Be sure to check outHow Video Game Consoles Workfirst for a general insertion to secret plan cabinet . ]

standardized to thePlayStation , the CPU in the N64 is aRISCprocessor . RISC abide forreduced instruction set reckoner , and means that the instructions and computations performed by the central processor are bare and fewer . Also , RISC scrap aresuperscalar– they can perform multiple instructions at the same time . This combination of capabilities , performing multiple instructions simultaneously and completing each instruction quicker because it is unproblematic , allows the CPU to do better than many bit with a much faster clock velocity .
To low yield cost , the graphics and audio processors are combined into a singleapplication specific integrated circuit , orASIC . Simply put , the ASIC which serve as the N64 ’s carbon monoxide gas - C.P.U. is a customise cow chip created to manage components that would otherwise be handled by multiple scrap .
Some special features of the N64 includeperspective correctionandtrilinear mip single-valued function . Perspective correctionmakes thetexture mapresize at the same rate as the object that it is represent on .
Trilinear mip mappingis a cool unconscious process . In this form of texture mapping , three size of each grain map are made , a big , a spiritualist and a modest version . In heart and soul , it substitute the visual aspect of an object with a more detailed image as you move nearer to the object in the plot . Let ’s take a looking at how it uses these function :
Environment mappingis no less awesome . Simple in conception , it means that musing of aim are deliver and mapped onto the contemplate Earth’s surface . The filmy amount of bet that is done by the graphics processor to determine the angle and transparency for each reflect object , and then render it in real time , is extraordinary . An incredible number of calculations have to chance for every single polygonal shape in a plot . And there can be over a hundred thousand polygons on the sieve at any give way time !
The games come on proprietaryROMshoused in pliant cartridges . When a game is put in the console , the trace come about :
Controller
The controller is the primary user interface for the N64 . With its trident configuration , it is probably the most unusual pattern for a accountant on the market today . The standard N64 controller has 14 push plus ananalogjoystick . The button include :
Although each clitoris can be configure to perform a specific and distinctive military action , they all work on the same principle . In essence , each release is a switch that completes a circuit when it is iron out . A small metal saucer beneath the button is pushed into contact with two strips of conductive material on the circumference display panel inside the controller . While the metal disk is in physical contact , it conduct electricity between the two strips . The comptroller feel that the circuit is shut and sends that data to the N64 . The CPU compares that datum with the pedagogy in the plot software for that button , and set off the appropriate response . There is also a metal disk under each arm of the directional pad . If you ’re playing a game in which promote down on the directional inking pad causes the character to crouch , a like strand of connections is made from the time you press down on the pad to when the fictional character crouches .
Theanalogjoystick works in a completely different way from the button described above . Twowheelsare pose at right angles to each other below the control stick . Whenever the joystick is moved , the two wheels turn slightly . bantam slots are stage around the perimeter of each wheel . The wheels are each mounted between anLED(Light Emitting Diode ) and aphoto cellular phone . Light from the LED , beam through the expansion slot in the roulette wheel on the jail cell , create a small amount of current . When the amount of low-cal changes , the grade of current change . By monitoring the output of each photo jail cell , the N64 can determine the exact slant at which the joystick is being held , and trigger the appropriate response .
Another feature article of the N64 controller is the ability to add choice via an expansion one-armed bandit on the bottom of the comptroller . A popular option is theRumble Pak , which providesforce feedback . This feature provides a tactile stimulation to certain action in a secret plan . For example , in a racing game , you might feel a jarring vibration as your car slams into the wall .
Force feedback is actually attain through the usance of a very common gimmick , a simple electricmotor . The shaft of the motor holds an unbalanced exercising weight . When power is append to the motor , it spin around the weight . Because the weight is unbalanced , the motor essay to shimmy . But since the motor is securely mount inside the Rumble Pak , the wobble translates into a throb vibration of the controller itself .
you could spare game and high-pitched scores by using one of the specialFlash memorycards . The card is inserted into the slot on the bottom of the N64 controller .
The N64 controller uses only three wires to connect to the cabinet . There ’s a ground conducting wire , another conducting wire that supplies +3 , 6 V of index , and a third wire that carries all data . The accountant get off the data for each push in sequence , and then receive data back from the console .
Games
The N64 is the only current system that use cartridges . There are advantages and disadvantages to this approaching :
Advantages

Although the N64 had only a few game available when it first number out , the phone number of title has grown to a considerable program library . Used games can be receive for less than $ 15 . Many of the new game can cost between $ 50 and $ 75 .
