Mark Cooksey is the unofficial name of the NES sound driver that Mark Cooksey created for the Nintendo Entertainment System. Unlike his earlier music, Mark Cooksey didn't program the music by hand. Instead, he would create MIDI files in Notator for the Atari ST, and then programmed a conversion tool to convert MIDI commands to the NES.

Some of his soundtracks use arpeggios. It is unknown if he actually wrote the MIDI files like that, or if he wrote chords on a single MIDI channel, which the driver converted to an arpeggio. It is most likely that in the original MIDI files, a single note was placed, and an arpeggio effect was assigned to the instrument patch when converted to the NES.

According to Cooksey, the instruments in his driver were meant to sound like flutes.


Release History

The first game to use Mark Cooksey's NES sound driver was Dragon's Lair, which was also the only game released in Japan to use his driver. The last game to use his NES sound driver was the European-exclusive Aladdin. A few unreleased games also utilized his driver. In the game Joe and Mac, his sound driver utilized DPCM drums, which Mark said may have been supplied by Richard Frankish.

Output

Mark Cooksey's NES sound driver outputs to both, the RP2A03 in North America and Japan, and RP2A07 in Europe.
