The '''NES Four Score''' and '''NES Satellite''' accessories allow four NES controllers to be connected to the NES's two controller ports.
Four player adapters are devices that plug into controller or expansion ports and provide additional ports. These ports can be used as alternatives to hardwired controllers or for multiplayer with more than 2 simultaneous players. Contemporary adapters allow some consoles to interface with up to 8 controllers. These adapters come in multiple forms, each with their own interfaces and limitations.
Controllers connected to this accessory are read using the same process as the [[standard controller]].
After the normal 8 reads from one port to get one controller data, 8 more are done to get another controller.


Note that the NES Four Score is not compatible with the Famicom 4-Players adapter, which connects the 3rd and 4th players to data bit 1 instead of bit 0. That functionality is described in greater detail on the [[standard controller]] article.
=Adapters=


D3 and D4 are not connected on the Four Score, so accessories like the [[Zapper]] and [[Power Pad]] will not work with it. The Satellite has a separate "GUN" mode switch to permit use of the Zapper. (The Four Score has a similar switch for 2-player mode, but it merely disables the multi-tap feature, it still can't pass the extra lines.)
=="Simple" Famicom adapters==
Because the Famicom only has one expansion port, a device such as the '''JoyPair''' or '''Twin Adapter''' is required to attach multiple controllers to it. Standard expansion controllers respond on D1 of $4016, and these passive multi-port devices redirect the second port to D1 of $4017. These may be used as players 3 and 4. In 1- or 2-player games for the Famicom, though, it is common to OR together the D1 and D0 bits of a joypad read to allow players to use external controllers as substitutes for the hardwired ones.


On both devices there are additional switches for turbo fire on the A and B button reports, which apply to all 4 ports.
The expansion ports on these multi-port devices do not pass through all of the signals and thus are limited in functionality compared to the console's expansion port. Because of this, many controllers are not compatible with these adapters.

==Hori 4 Players Adapter==
 
The '''Hori 4 Players Adapter''' is a Famicom expansion port device that provides 4 ports, usable in 2- and 4-controller modes selected using a switch. In 2-controller mode, ports 1 and 2 on the adapter function exactly like a "simple" Famicom adapter, and ports 3 and 4 are disabled. In 4-controller mode, ports 1 and 3 are multiplexed onto $4016 D1 and ports 2 and 4 onto $4017 D1. The first 8 reads from an address provide the joypad 1 D1 report from the first controller, the next 8 reads the joypad 1 D1 report from the second controller, and the next 8 reads a signature unique to that address. The read counter is reset as long as OUT0 is 1. The same connection limitations of the "simple" adapters still apply in 4-controller mode, which combined with the 8 read limit restricts the set of usable contemporary controllers to those compatible with the standard controller.

The Four Score is an adapter that plugs into both NES controller ports and provides 4 ports, usable in 2- and 4-controller modes. This device is nearly identical to the Hori 4 Players Adapter, differing in that D0 is used instead of D1 and the addresses' signatures are swapped. This device also provides two turbo switches.

The $10 and $20 signatures are sent most significant bit first. They can be used to detect 1. whether the Four Score switch is in the 4 player position and 2. whether a DMC sample fetch caused a [[Standard controller#Evil Details|bit deletion]].
Note: ''Joypad D0'' refers to the data normally available on $4016 or $4017 bit 0. Unlike the Famicom expansion port, NES controller port wiring is relative to the port used, so while a controller normally chooses which data inputs to use, it does not choose whether those are joypad 1 or joypad 2.


Controllers #3, #4, and the two signatures are only sent when the Four Score switch is in the 4 player position.  When the switch is in the 2 player position those reads get the same result as a normal controller, either $00 or $FF depending on the controller.
===Turbo===


== Hardware ==
The Four Score includes separate turbo enables intended for the A and B buttons. Each of these applies universally to all attached controllers and in both 2- and 4-controller modes. These turbos force their respective bits to 0 at a fixed rate by ANDing with a mask that alternates between 0 and 1, making a held button appear as though it is being rapidly pressed and released. After a strobe, the A turbo applies to the first read of each controller's report and the B turbo to the second read. In 2-controller mode, each turbo also applies again after every 32 additional reads, causing toggles in the stream of 1's that follow the report from official controllers.


If you find yourself in the situation where you want to use the Four Score electrical interface for a project, but don't want to use up a Four Score, you can simply use six shift registers instead. Daisy-chain three shift registers together:
The toggle rate is based on the Four Score's internal clock and is approximately 2 frames.

From [http://bootgod.dyndns.org:7777/search.php?peripherals_op=OR&peripherals%5B%5D=fourplayer&group=groupid NesCartDB]:
These adapters can be used in combination with each other on the AV Famicom for up to 8 controllers, or on the Famicom with the hardwired controllers for up to 6. Because nonstandard controllers are not compatible with 4-controller modes, using them reduces the maximum possible controller count, but if a single nonstandard controller such as a mouse is desired, it can be used with a "simple" adapter alongside up to 6 standard controllers on an AV Famicom using a Four Score in the NES controller ports, a "simple" adapter in the expansion port, and a Hori 4 Players Adapter with controllers in ports 1 and 3 in the other "simple" adapter port.

Four player adapters are devices that plug into controller or expansion ports and provide additional ports. These ports can be used as alternatives to hardwired controllers or for multiplayer with more than 2 simultaneous players. Contemporary adapters allow some consoles to interface with up to 8 controllers. These adapters come in multiple forms, each with their own interfaces and limitations.

Adapters

"Simple" Famicom adapters

Because the Famicom only has one expansion port, a device such as the JoyPair or Twin Adapter is required to attach multiple controllers to it. Standard expansion controllers respond on D1 of $4016, and these passive multi-port devices redirect the second port to D1 of $4017. These may be used as players 3 and 4. In 1- or 2-player games for the Famicom, though, it is common to OR together the D1 and D0 bits of a joypad read to allow players to use external controllers as substitutes for the hardwired ones.

The expansion ports on these multi-port devices do not pass through all of the signals and thus are limited in functionality compared to the console's expansion port. Because of this, many controllers are not compatible with these adapters.

(All other JoyPair pins not connected)

Hori 4 Players Adapter

The Hori 4 Players Adapter is a Famicom expansion port device that provides 4 ports, usable in 2- and 4-controller modes selected using a switch. In 2-controller mode, ports 1 and 2 on the adapter function exactly like a "simple" Famicom adapter, and ports 3 and 4 are disabled. In 4-controller mode, ports 1 and 3 are multiplexed onto $4016 D1 and ports 2 and 4 onto $4017 D1. The first 8 reads from an address provide the joypad 1 D1 report from the first controller, the next 8 reads the joypad 1 D1 report from the second controller, and the next 8 reads a signature unique to that address. The read counter is reset as long as OUT0 is 1. The same connection limitations of the "simple" adapters still apply in 4-controller mode, which combined with the 8 read limit restricts the set of usable contemporary controllers to those compatible with the standard controller.

Note: Joypad 1 and joypad 2 are names used on the controller-side Famicom expansion port pin interface, as compared to $4016 and $4017 on the CPU side. While joypad 1 normally connects to $4016, this adapter routes each controller's joypad 1 /D1 to $4016 or $4017 as needed.

Four Score

NES Four Score

The Four Score is an adapter that plugs into both NES controller ports and provides 4 ports, usable in 2- and 4-controller modes. This device is nearly identical to the Hori 4 Players Adapter, differing in that D0 is used instead of D1 and the addresses' signatures are swapped. This device also provides two turbo switches.

 24+   - (Always 1)

Note: Joypad D0 refers to the data normally available on $4016 or $4017 bit 0. Unlike the Famicom expansion port, NES controller port wiring is relative to the port used, so while a controller normally chooses which data inputs to use, it does not choose whether those are joypad 1 or joypad 2.

Turbo

The Four Score includes separate turbo enables intended for the A and B buttons. Each of these applies universally to all attached controllers and in both 2- and 4-controller modes. These turbos force their respective bits to 0 at a fixed rate by ANDing with a mask that alternates between 0 and 1, making a held button appear as though it is being rapidly pressed and released. After a strobe, the A turbo applies to the first read of each controller's report and the B turbo to the second read. In 2-controller mode, each turbo also applies again after every 32 additional reads, causing toggles in the stream of 1's that follow the report from official controllers.

The toggle rate is based on the Four Score's internal clock and is approximately 2 frames.

NES Satellite

NES Satellite

The NES Satellite is a 4-controller wireless adapter similar to the Four Score. Specific details are not yet known. Instead of a mode switch for 2 or 4 controllers, the NES Satellite has a mode switch selecting between standard controllers and the Zapper. Like the Four Score, it also features A and B turbo switches.

Hardware

Inside the Four Score and 4 Players Adapter is a 22-pin DIP labeled FPA-S01. This IC consists of a decoder and one set of shift register, 5-bit counter, and multiplexer per joypad address, allowing each address to return the 8-bit contents of joypads 1 and 3 or 2 and 4 in series, followed by the signature byte.

In case you want to build a four player adapter into an arcade cabinet or some other permanent installation, you don't need to use a Four Score or other adapter: you just need six total shift registers. The inputs to these shift registers are parallel, so you need separate wires for each signal, like from SMS or ZX Spectrum controllers.

5+ controllers

These adapters can be used in combination with each other on the AV Famicom for up to 8 controllers, or on the Famicom with the hardwired controllers for up to 6. Because nonstandard controllers are not compatible with 4-controller modes, using them reduces the maximum possible controller count, but if a single nonstandard controller such as a mouse is desired, it can be used with a "simple" adapter alongside up to 6 standard controllers on an AV Famicom using a Four Score in the NES controller ports, a "simple" adapter in the expansion port, and a Hori 4 Players Adapter with controllers in ports 1 and 3 in the other "simple" adapter port.

Incompatible Games

This section lists games that provide four player game modes without supporting a four player adapter. They are explicitly enumerated here because various lists, including one in Wikipedia, frivolously keep listing (and re-adding after an edit to remove them) these games as supporting a four player adapter.

  • Championship Bowling: Manual clearly states "Players One and Three use Control Pad 1, and Players Two and Four use Control Pad 2".
  • Jeopardy! series: Players 1 and 3 share controller 1.
