Cho Ren Sha 68K was created by designer, programmer, and artist Koichi "Famibe no Yosshin" Yoshida. These included
Metal! Itō (1990),
V5 Denden (1991), and
Zacner II (1993). In 1993, Yoshida started developing the game by establishing a code library for the X68000, as guidebooks about its hardware published late in its lifespan galvanized the computer's
doujin and
freeware scenes. One of Yoshida's main goals in his design concept for
Cho Ren Sha 68K was to evoke a fun sense of destruction and make shooting exciting. He recalled that the game was influenced by various shooters such as
Tatsujin Ō,
Batsugun,
Battle Garegga, among others. Yoshida wanted to recreate a technique from older shooters where enemies are dealt more damage up close through various
mechanics, and he was looking for a balance reminiscent of
Star Force. These mechanics contradicted Yoshida's plans for the game, so he decided to constantly reduce the size of enemy
hitboxes, resulting in some enemies being redrawn to fit their hitboxes. He had been writing original music for the X68000 and uploading it via a network system during his high school period. He took over scoring the soundtrack for the project when a partner known only by the pseudonym "Zuruyan" introduced him to Yoshida, who was looking for a composer during Pasoket, a
doujin soft sales event held in
Osaka by the company of the same name. Kashiwagi drew influence from
Viewpoint (1992) and
Battle Garegga for the game's music. He stated that he made his own
Eurobeat for the first stage, taking inspiration from
Namie Amuro's song
Taiyou no Season, and regarded the third stage and boss themes to be his favorites. A soundtrack album for
Cho Ren Sha 68K was released in Japan on August 14, 1998 by Denkai Laboratory, an independent
circle formed in 1995 by Kashiwagi and Zuruyan. In 2003, Denkai Laboratory distributed a three-CD album at the 64th
Comic Market (Comiket) subtitled
Complete Edition, containing the game's original soundtrack as well as arranged and reworked tracks. In 2006, the
Complete Edition album was reissued through
D4 Enterprise's EGG Music digital service. == Release ==
