Space Channel 5 is a console game, which was first released for the Sega Dreamcast on December 16, 1999. The producer of this game is Tetsuya Mizuguchi, the man who is also behind Sega Rally. It features the character Ulala (a reference to the phrase "ooh la la"). The game is similar to PaRappa the Rapper and earlier memorization games like Simon Says where the computer shows a sequence of moves - dance steps in this case - and the player must copy them successfully to advance. The original Space Channel 5 was published in Japan, the US and Europe on the Dreamcast but the sequel, Space Channel 5: Part 2 was released in Japan for the Dreamcast and PlayStation 2, and in English only on the PlayStation 2 as part of Space Channel 5 Special Edition.

Space Channel 5: Ulala's Cosmic Attack was released for the Game Boy Advance in 2003.

In early 2003, Lady Miss Kier , formerly of the band Deee-Lite, initiated a lawsuit against SEGA corporation for allegedly stealing her former persona and using it as the basis of a video game character. The lawsuit was based on accusations of copying her look of knee-high boots, short skirts and a pink ponytail, for SEGA's Ulala character design. Lady Miss Kier (whose real name is Kierin Kirby ) claims that SEGA offered to pay her $16,000 to license her name, image and songs for the game, though she rejected their offer. Kirby later learned that the videogame maker went ahead and used her resemblance anyway, and she decided to initiate the lawsuit, seeking more than $750,000 in damages.

A minigame called Dance was included in the 2004 Nintendo DS handheld game Feel the Magic: XY/XX which has a near-identical format to Space Channel 5. If the game is played with a Space Channel 5: Ulala's Cosmic Attack Game Boy Advance cartridge in the system at the same time, Ulala's hairstyle could be unlocked for the female lead.
