Ken Moore is an unofficial name of the sound driver used at Sculptured Software. According to Sculptured Software's main composer Paul Webb, it was programmed by Ken Moore.

Paul would write the music on his keyboards. However, he doesn't remember exactly how his compositions were converted over to the NES. According to Mario Gonzalez, the music was done by him using a sequencer and then typing the music in assembly on a computer.

Ken Hedgecock says that he used a piece of software by Yamaha, but doesn't remember the name of it. Graeme Devine said something about using AdLib Visual Composer as well.

Release History

The first game released to use Sculptured's sound driver was Spot: The Video Game, developed by Virgin Games.

While Sculptured Software was developing The Empire Strikes Back for NES, members of Active Enterprises were taken to Sculptured and used their development tools to make Action 52 and Cheetahmen II. Mario Gonzalez got to use their sound driver to compose the music and sounds to Action 52 and Cheetahmen II.

The sound driver was used in games released in North America, Europe, and Japan.


Ken Moore's sound driver outputs to the RP2A03 and RP2A07. The DPCM channel is used in rare instances (Day Dreamin' Davey and Monopoly), but not for music. The driver utilizes the triangle channel with the noise channel to produce better percussion, but is also used as a melodic and bass line.
