controller port as standard, the Multitap was a necessity for games that supported more than one player. As a result, various inexpensive alternatives to the Multitap were released for the PC Engine by third-party companies, such as the Battle Tap by Big Club and the Joy Tap 3 by Hudson Soft, which featured less controller ports than the first-party Multitap, but these were gradually phased out as more games started to allow up to five players. The first PC Engine game to allow more than two players simultaneously was Pro Tennis: World Court in August 1988 (ten months after the launch of the system), which allowed up to four players in a doubles match, while Dungeon Explorer in 1989 was the first game to fully allow up to five players. The Multitap was redesigned into the TurboTap for the North American market with the launch of the TurboGrafx-16 in 1989, and later as the DuoTap for the TurboDuo in 1992 (the different models were due to the change in controller ports between the TurboGrafx-16 and the TurboDuo). Hudson Soft manufactured the Super Multitap, a multiplayer adapter for the Super NES in 1993. The adapter connects to the second controller port of the SNES control deck (leaving the first one free), resulting in a total of five controller ports (much like the original Multitap for the PC Engine). It was produced primarily for Super Bomberman, which had a prior installment on the PC Engine (simply titled Bomberman) that featured a five-player battle mode, although the SNES game only supported up to four players (the series did not support five players on the SNES until Super Bomberman 3, which was released only in Japan and the PAL region). The Super Multitap has a switch for 2P Mode and 5P Mode, allowing it to remain connected into the console without affecting incompatible games. While no Nintendo-produced version of the peripheral was ever produced (nor were there any first-party games that supported it), various other SNES multitaps were later produced by other companies (both, licensed and unlicensed) such as the Hori Multitap (released by Bulletproof Software in North America as the Super Links) and the Multi-Adaptor Auto. One particular unlicensed model, the Tribal Tap 6 Player Adaptor by Naki, added a fraudulent sixth controller port that was promoted as a selling point against competing multitap models, even though no licensed SNES game ever supported
