Kinesoft Development Corporation was a British video game development company founded by Peter Sills in 1991. Mark Achler joined the company in 1994 to serve as president. Along with Director of Technology, Andrew Glaister, Sills developed the concept which became known as Exodus, a video-game development environment for Windows 95. Andrew Glaister took this concept and developed it.

Exodus caught the attention of IBM, Intel, Sega, and Microsoft. Microsoft then used the basic concepts and their relationship with Kinesoft to develop a new set of technologies called DirectX which now forms the basis of all gaming under Windows.

In 1995-05-25, Kinesoft and SoftBank entered into the "Game Porting Agreement". Under the terms of that agreement, SoftBank was to provide Kinesoft with a certain number of console games to be "ported" to a PC platform; the "porting" involves translating pre-existing video games from the console platform to the personal computer platform. The games were to be published by GAMEBANK Corporation, a joint venture company established by SoftBank and Microsoft to bring console titles to Windows 95 for the Japanese marketplace by using its unique talents and tool-sets to convert existing Sega Genesis titles. In the US, some of these ports were published by Interplay. These ports were later expanded to include Nintendo and some early Sony PlayStation titles as well.
