Rally-X was created by
Namco and designed by Hirohito Ito, with hardware developed by Kouichi Tashiro. It was produced as a successor to
Head On (1979), an older
arcade game from
Sega that similarly involved collecting items in a maze while avoiding enemy cars that pursued the player. before receiving a wide release on October 3, 1980. When preparing to release the game overseas, Namco believed
Rally-X had more foreign appeal than
Pac-Man with its audiovisual presentation and challenge, which it believed American audiences would prefer to the simplicity and "cuteness" present in
Pac-Man. Namco presented
Rally-X at the 1980 Amusement & Music Operators Union (AMOA) tradeshow in
Chicago, Illinois, alongside
Pac-Man,
King & Balloon, and
Tank Battalion. An often-repeated story is that out of the games presented, specifically
Pac-Man, the attending industry analysts believed
Rally-X was the stand-out and the one destined to be successful.
Midway Manufacturing, the video game division of
Bally Manufacturing, agreed to distribute
Rally-X and
Pac-Man in North America. Dave Marofske, the president of Midway, believed the two had the most potential out of the four Namco games presented. Midway released
Rally-X in North America in February 1981 in upright, tabletop, and cabaret cabinet variations.
Conversions A home conversion of
Rally-X was released for the
VIC-20 in Japan in 1981. The port was developed by
HAL Laboratory and published by the Japanese division of
Commodore International. Due to licensing restrictions, HAL changed the game's characters to mice and cats and released it in North America as
Radar Rat Race. which was released in Europe by Argus Press Software under the
Bug-Byte name. Dempa Shinbun developed versions for the
Fujitsu FM-7,
MZ-1500, and
Sharp X1 computers in Japan the same year.
Rally-X remained relatively obscure for many years until 1995, when it was included in the
PlayStation compilation
Namco Museum Vol. 1 along with six other Namco arcade games.
Rally-X has been included in several
Namco compilations including
Namco History Vol. 2 (1997),

Namco Museum 50th Anniversary (2005),

Rally-X was re-released for arcades as part of
Namco Classic Collection Vol. 2. It has also appeared in several Namco "
plug'n play" game controllers from
Jakks Pacific.
