A Joystick is a device to let you manually control direction of movement in an arcade game. This article describes the most common types of joysticks used in arcade cabinets and game systems.

Conventional Digital Joysticks: 8-way, 4-way & 2-way
Conventional joysticks are fairly simple devices without which Pac-Man would be ghost-fodder. When the joystick shaft is moved in any direction, the lower end of the stick is levered in the opposite direction and makes contact with switches, these switches are what tells Pac-Man to move and in which direction.
By using four switches at the base of the joystick, 8 directions can be achieved; Up, Down, Left and Right as well as the four corner positions which are triggered by two switches being activated simultaneously. When you press the joystick diagonally up and to the right, both the "up switch" and the "right switch" are triggered simultaneously, indicating your diagonal move. Joysticks like this are known as 8-way joysticks.
Some joysticks were designed to specifically prevent the player from moving diagonally. For example, joysticks used in Pac-Man and Donkey Kong both have physical restrictions preventing the joystick from moving to the diagonals. Since the joysticks only allow movement in 4 directions (Up, Down, Left and Right) they are known as 4-way joysticks. While it is possible to use an 8-way joystick when playing 4-way games, it's not recommended, as accidentally hitting a diagonal with the joystick can create problems during gameplay, such as causing Mario to stand still or Pac-Man to become confused between moving up or to the side.
Other games, such as Defender, Joust, Mario Brothers and Galaga, used a 2-way joystick since movement was only necessary from left to right or up to down. While it may not be historically accurate, it is generally not a problem to use either 4-way or 8-way joysticks for these games.
Standard 8-way only joysticks:
- Happ Competition
- Happ Ultimate (review) (can be ordered 2, 4, or 8-way)
- Wico 8-way Leafswitch Joystick (discontinued).
Standard 4-way only joysticks:
- Happ Ms.Pac/Galaga Reunion
- Betson Ms.Pac/Galaga Reunion
- Happ Ultimate (review) (can be ordered 2, 4, or 8-way)
- Wico 4-Way Leafswitch (discontinued).
8-Way to 4-Way Switchable Joysticks
Many 8-way joysticks that are sold can also be set to work in 4-way mode. There are two basic methods to change modes:
1) Changing a restrictor plate that only allows the joystick handle to be pushed in certain directions; or:
2) Changing the actuator (that's the small piece on the bottom end of the joystick shaft that makes contact with the switches) to only allow contact with one switch at a time.
Restrictor plate changes convert the joystick to "true" 4-way operation, and will give the best play. Actuator changes do not keep the handle from moving into the diagonal positions, this method only keeps the switches from being activated. The result is a "dead spot" in the corners, where the stick can be pushed, but no switches are hit. This is not much better than playing in standard 8-way mode, and is not reccomended. Adjusting these joystick usually involves opening up your control panel so you can access the lower section of the joystick base. Some models using a restrictor plate can be easily changed by hand once the control panel is open, while some others require the use of basic tools, like a screwdriver.
Joysticks that can be set to 4-way or 8-way operation via an actuator swap include:
Joysticks that can be set to 4-way or 8-way operation via the restrictor plate include:
- Suzo 500 (aka Euro-Stik or Omni-Stik), Ultimarc T-Stik, Ultimarc Mag-Stik, Ultimarc J-Stik, Sanwa JLF-TP-8YT, Seimitsu LS-32.
In the last few years, some companies have added to this feature to allow the joystick to be switchable from above the control panel in some way. This makes it simple for anyone to switch the joystick between 4-way to 8-way from game to game, without having to access 'the guts' of the control panel.
Conventional joysticks that can be switched from above the control panel like this include:
TRON joysticks
TRON arcade machines had 8-way trigger joysticks that were restricted to make it difficult to go diagonally. This was necessary because some of the four games in TRON were developed for 4-way sticks, while others were able to use 8-ways. More on TRON joysticks here.
Also see Wiring Push Buttons and Conventional Digital Joysticks.
Unconventional Digital Joysticks
Suzo Inductive Joystick
Instead of using conventional microswitches, Suzo Inductive sticks employ the use of a ferrite ring at the base of the joystick shaft. An oscillating magnetic field is induced in the ferrite ring by the main coil in the centre of the PCB around the opening. This oscillating field within the ferrite ring induces a current in one or more of the eight smaller coils on the PCB. The exact position of the joystick is determined by the strength of the current in each coil. A potentiometer can be adjusted so that diagonal positions are ignored (resulting in 4-way output) or that diagonals are accepted (resulting in 8-way output.) The sensitivity of 8-way operation can be refined using the potentiometer. It is completely silent and is easily switchable between 4-way and 8-way using the aforementioned pot located on the bottom plate of the joystick.
It has an octagonal restrictor to assist in locating the desired directions. There are 6 pins for the connection which are labeled on the bottom plate of the joystick: Ground/Earth; +5 VDC; Left; Right; Up; Down. It is a short throw joystick with a max travel of 5 degrees from centre. The joystick is designed to be undermounted without taking the joystick apart; this requires a hole in the panel approx 44 mm or 1 3/4". The joystick handle was produced in two sizes, a 32 mm ball handle (suitable for cocktail cabinets), and a 38 mm ball handle. This joystick is no longer produced but as of May 2006 some were still available from Groovy Game Gear and TNT Amusements.
Happ Perfect 360 (P360)
The Perfect 360 joystick is an optical joystick, which means that the position of the handle is read by optical switches, instead of conventional leaf switches or microswitches. This gives near-silent operation, as the handle & actuator never touch anything.
These sticks have a very smooth feel, largely due to the "no touch" action. P360 joysticks have a round restrictor, instead of the more common square restriction found on many other modern joysticks. This round restriction adds to the smoothness factor, because there are no corners to feel.
Connection- P360 joys require a little more effort to hook up- in addition to the Up, Down, Left, Right and Ground connections on standard joysticks, the P360 also needs a +5 volts connection. This is easy enough to get, as encoders such as the I-Pac and KeyWiz provide a +5v header. PC power supplies produce +5v on the red wire of the drive connectors. There is also +5v power available on USB & PS2 cables. +5 volt power is easy to find.
History- The Perfect 360 started out as an aftermarket add-on kit for Wico leafswitch joysticks. Models were later added to the product line to convert Happ Super, Competition, and Ultimate sticks, and possibly others as well. Happ eventually bought the rights to the P360 technology, and discontinued the kits. Happ began producing a complete stick instead, with the top half of a Wico joystick base (no longer sold by Wico by then) mated to a P360 bottom half.
Interchangability- P360 handles and Wico handles have been found to be interchangable. There are also replacement handles available from SlikStik. Wico Pear-top sticks used the same pivot cones and spacer sleeves.
Ultimarc UltraStik 360 (U360)
This offering from Ultimarc operates on similar principals to an inductive joystick, but offers many more custom features. Using its USB interface and the provided software, it's possible to easily switch the joystick between 2-way, 4-way, 8-way, analog and even 4-way diagonal (Q*Bert) modes. User defineable custom modes are also available.
When used via USB, Windows thinks of this joystick as a gamepad and allows you to hook-up 8 buttons straight to the joystick; so no seperate encoder (IPac, Keywiz etc) is necessary.
49-Way Joysticks
Once used in a small handfull of Williams, Midway and Atari games, 49 way joysticks live in a no-man's land between digital and analog joysticks. 49-way joysticks do not, as the name might seem to imply, point in 49 different directions. The number 49 comes from the number of positions the stick can report to the game hardware, including positions somewhere between "dead center" and "pushed all the way". Imagine a 7x7 grid (that's 49 squares) and you've got it. Games that originally used this hardware benefited from the extra info the joystick could report by allowing the player to control the on-screen character with more precision- both in the form of better directional control (24 discrete directions possible, if you count dead center), and 3 levels of speed control, based on how far from center the stick was pushed. For example, in SiniStar, the player can make the ship move faster or slower, by varying how hard they push the stick, and the ship's movement is not limited to just 8 directions. Attempting to play this game (or others that originally used 49-way sticks) with a standard 8-way digital joystick tends to be frustrating- SiniStar is a very difficult game in the first place; take away the speed control and limit yourself to 8 directions, and it's really, really hard. More info on 49-way joysticks can be found at What are 49-Way joysticks? by URebelScum
Games that originally used 49-way joysticks include:
- SiniStar
- Blaster
- Arch Rivals
- Pigskin 621 A.D.
- Blitz
- Blitz '99
- Blitz 2000
- NFL Blitz 2000 Gold Edition
- NBA Showtime
- SportStation
- Gauntlet: Legends
- Gauntlet: Dark Legacy
For home gaming purposes, when paired with the GP Wiz49 controller from GroovyGameGear, these analog style joysticks have become a popular all-around stick. Using the GP-Wiz's various DRS modes, these joysticks can be easily switched between 8-way, 4-way, 2-way (vertical), 2-way (horizontal) and diagonal (Q*Bert style) modes without having to physically change the joystick hardware. This allows these sticks to be used to play any digital joystick games well. In addition, the two 49-way modes allow play for games that originally used 49-way sticks (and have emulator support that goes beyond 8-ways- not all 49-way games do), and also will play well for some games that originally used analog or Hall-Effect joysticks.
For those with a penchant for soldering here's a circuit on Arcadecollecting.com that allows a 49-way to be connected with an an analog interface (Dualstrike hack etc).
There are three varieties of 49-way joystick: Williams, Midway, and Happ.
The Williams are easy to distinguish- they use a distinctive rubber centering "spider" on the bottom, and have balltop handles. Red balltops come from SiniStar; Orange come from Arch Rivals. There are also Williams optical sticks out there with Turquoise and Yellow balltops. These look like 49-ways, complete with centering spider. However, these sticks do not have as many optics, and the pin connector is different, with fewer pins. These sticks are 8-way only. Turquoise ones most likely come from Bubbles, however, some early Joust games shipped with Turquoise and Yellow optical sticks.
The Midway and Happ 49-ways are very similar, in fact the Happ is just the Midway stick with a minor re-design. (Happ bought the rights to a lot of Midway's parts business several years ago.) The Midway sticks have a smaller diameter shaft, and the centering grommet has a correspondingly smaller hole. Both have a black bat top handle. Replacement handles are available in a variety of colors (Happ variety only) at GroovyGameGear.
Analog Joysticks
Analog joysticks are not bound by the limits digital joysticks face. Digital joysticks can only point in 8 (or fewer; see above) directions, or no direction at all (centered). Analog joysticks can point in (theoretically) an unlimited number of directions. Furthermore, Analog joystics can discern how far the handle has been pushed from the center position. Games take advantage of these properties to give the player a much greater level of control over their on-screen character. For example, the bird in Road Runner can run in more than just the 8 standard directions, and how far the player pushes the joystick from center determines how fast the Road Runner runs.
Most analog sticks use a pair of potentiometers, one to measure left-to-right movement (the X-axis), and one to measure forward-and-back movement (the Y-axis). A few games, however, used a "Hall Effect" stick. Hall effect sticks use Hall sensors and magnets to read the postion of the stick. The end result is the same, though- both types report to the game which direction and how far the stick is being pressed.
While the actual resolution of an analog joystick may be theoretically unlimited, the standard for analog joysticks connected to a PC is 256x256. Compare this to the 7x7 resolution of a 49-way joystick, or the 3x3 resolution of a standard 8-way joystick. This explains why it is difficult to play games that originally used analog controls with a standard 8-way stick; the stick simply can't control the on-screen character the way it was intended to be controlled. A 49-way stick is sufficient for some games that originally used analog controls, but not all of them. Road Runner, for example, can be adequately controlled with a 49-way joystick, as that stick would give the bird 24 directions to run in, and four speeds (including stopped)- which ought to be enough to outwit that dumb coyote. Star Wars, on the other hand, cannot be played well with a 49-way, as that stick will only aim the X-Wing's blasters at 49 equally spaced spots on the screen, leaving Tie Fighters that are in-between those spots un-shootable. (Star Wars actually used an analog Flight Yoke, rather than an analog joystick, but these controls are electrically identical, and actually interchangeable as far as the game is concerned.)

Rotary Joysticks
There are two types of rotary joysticks that often get confused: Mechanical rotary sticks, and optical rotary sticks. Either can be interfaced with a PC.
Mechanical rotary sticks are the type that most people remember from games like Ikari Warriors. They have a 12-position rotary switch attached to the bottom of the joystick, which is turned by rotating the handle. Each turn of the handle is accompanied by a clicking sound, and distinct tactile feedback that lets the player know that a turn has been registered.
The SNK games used a stick called the LS-30, with yellow octagonal tops. The Data East games used the same sticks, but with a yellow barrel shaped top. Wico used to make a rotary stick, with a yellow balltop These were basically standard Wico leaf sticks, with the rotary switch added to the bottom. Happ still sells a mechanical rotary stick, which is basically a Happ Super with a rotary switch added to the bottom.
Optical rotary sticks have an optical encoder wheel, similar to a spinner, instead of a rotary switch. Caliber .50 used a stick called the Loop-24, with green octagonal tops.
Most games that used rotary joysticks used the rotary function to determine which direction the on-screen character was aiming. This allowed the player to shoot in a different direction from the direction of motion, all with one hand.
