Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Cybersphere is a "ball and paddle" game similar to Arkanoid. The game and its sequel (Cybersphere Plus) have recently been released as freeware by the designer. It was designed by Clay Hellman and published by Psycon Software. Cybersphere uses OPL3 FM sound synthesis chip and therefore may require a use of an emulator such as DOSBox for the audio to work.
