more than five players. Two independently developed multitaps were released for the Sega Genesis also in 1993. The 4-Way Play (which utilized both controller ports) was developed by Electronic Arts without license from Sega and was made specifically for their lineup of sports games (such as Madden NFL '94), whereas the Team Player (known as the SegaTap in Japan) was developed by Tengen for Gauntlet IV and sold by Sega as a first-party product. In contrast to the 4-Way Play, the Team Player only required one controller port (leaving an additional port free for a fifth player, much like the Super Multitap) and also acted as a splitter that allowed users to switch between multiple input devices (such as a mouse or a light gun) connected to the console at the same time. The original model of the Team Player (MK-1654) was incompatible with games that required the 4-Way Play, so a revision (MK-1647) was later produced that solved this issue by adding a second controller cord and an "Extra" setting for 4-Way Play compatibility. While most Team Player-compatible titles only supported up to four players (with some games such as Columns III supporting up to five), Konami's Double Dribble: The Playoff Season and Sega's Egawa Suguru's Super League CD (a Japan-exclusive baseball game for Mega CD) both allow up to eight players with the use of two Team Player adapters (one in each controller port). In addition to these multitaps, Codemasters released a series of Genesis cartridges known as the J-Cart with two additional controller ports installed on them, allowing users to plug in additional controllers on them without the need of an adapter. A total of six games were released in J-Cart format. 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 parallel port and provide two additional ports for use. Earlier, the Amiga version of Bomberman, Dynablaster had already included support for a similar device, as demonstrated on Season 2, Episode 5 of TV's GamesMaster. Fifth generation The original PlayStation Multitap was one of the earliest peripherals released for the platform. It featured not only four additional controller ports, but also four memory card slots for each of them as well. Like
