Multi-tap also refers to a text-entry system for mobile phones.''

Hudson Soft released a Super Famicom Multitap in the shape of Bomberman's face.
A 'multitap' is a
video game console peripheral that expands the number of
controller ports available to the player, thus allowing additional controllers to be used in play. A multitap often takes the form of a box with three or more controller ports which is then connected to a spare port on the console itself.
Mainly
sports games supported multitaps due the multiplayer aspect of some sport games, though some
RPGs and
first person shooters have taken advantage of multitap support.
History
8-bit era
The first multitap device to be produced was by
NEC-
Hudson Soft for the PC-Engine /
TurboGrafx-16. The PC-Engine is one of the few consoles to have been originally fitted with only one controller port. To make "multiplayer" gaming possible, one had to purchase the ''Turbo Tap'', expanding the PC-Engine to 5 players.
The
Nintendo Entertainment System (NES) saw two official multitaps, the
NES Four Score and the wireless
NES Satellite.
16-bit era
Electronic Arts - Sega's most important 3rd party developer for the
Sega Mega Drive/Sega Genesis - released the
4 Way Play to make four-player sports games possible. Shortly after that, Sega released its own four-player adapter which was incompatible with EA's adapter. The way out of that difficult situation was a slightly redesigned adapter by Sega, which supported both the Sega and the EA formats.

J-Cart with two build-in controller ports
Codemasters developed a quasi-multitap for the
Mega Drive called the
J-Cart, first released in
1994.
[1] The game would have two extra joypad ports built into the cartridge itself, thus negating the need to buy extra hardware (beyond two more joypads) to play four-player games.
Nintendo, in conjunction with
Hudson Soft, released in
1993, the ''Super Multitap'' for the
Super Nintendo, it could be purchased bundled with the well regarded game ''
Super Bomberman'' which helped establish the popularity of the peripheral. Several other compatible
SNES Multitaps followed. With the success of the Nintendo device, the term "multitap" became synonymous with similar devices.
A few games released for the
Amiga home computer system after
1995 included support for custom-built multitaps. Instructions for how to build a multitap were included in the manual to classic Amiga racing sequel ''
Super Skidmarks''. The Amiga multitap would plug into the computer's serial port and provide two additional ports for use. Earlier, the Amiga version of Bomberman,
Dynablaster had already included support for a similar device.
32-bit era and beyond
Multitaps were released by
Atari for the
Jaguar,
Sega for the
Saturn and
Sony for its
PlayStation and
PlayStation 2 consoles.
The PlayStation multitaps also allow the same number of memory cards as controllers. In games such as , this allows all players to insert memory cards and track their personal statistics.
In recent years the multitap has become an increasingly redundant peripheral, with most console designers preferring to simply expand the number of controller ports on the console itself. While the first console to actually feature 4 built-in controller ports was the
Bally Astrocade, that feature would not be widely used again for well over a decade until the arrival of the
Nintendo 64. Subsequent consoles, with the exception of Sony's PlayStation 2, all included four ports as standard. With the advent of standard wireless controllers in the next generation of consoles, the days of the traditional multitap seems to come to an end.
