Arsys Software, Inc.

Arsys Software was established in November 1985 by a group of former Technosoft staff. Their first game, Wibarm, was released in 1986, and in the following years the company produced a number of titles, including Star Cruiser (1988) and Knight Arms (1989), as well as ports of titles such as Prince of Persia, Tenka Tōitsu, and Spindizzy II.

By July 1996, the company consisted of only Kotori Yoshimura and a handful of other staff, and the company's name changed to Cyberhead. Cyberhead contributed to the development of several titles, including Gran Turismo and Omega Boost, but eventually closed in 2001.
