I play Cosmo Gang on my US Snes for SHMUP Saturday.
Cosmo Gang: The Video is a fixed shooter arcade game that was released by Namco in 1991; it runs on Namco System 2 hardware, and is based on a redemption game called Cosmo Gang that was released in the previous year (and licensed to Data East for US manufacture and distribution). A sequel called Cosmo Gang: The Puzzle was released in 1992 - and an adaptation of it with Pac-Man characters was released in 1993 for the Super Nintendo Entertainment System and Sega Genesis under the title Pac-Attack.
Namco later developed a Super Famicom conversion of this game, released on October 29, 1992; this version was re-released for the Wii Virtual Console on August 4, 2009. Although the arcade version was released in the United States both console releases were Japan-only.
