Yoshiaki Inose (NES Driver)
Yoshiaki Inose is the unofficial name of the NES sound engine programmed by Tecmo programmed Yoshiaki Inose. It was used in only four games; Chester Field, Mighty Bomb Jack, Super Star Force, and Tsuppari Oozumou.
Though the driver was programmed by Yoshiaki Inose, he did not write music or sound effects, and therefore didn't use the driver. Keiji Yamagishi used it to compose his first game Tsuppari Oozumou, Michiharu Hasuya and Tsukasa Masuko both used it for Mighty Bomb Jack, and Mikio Saito used it for the games Chester Field and Super Star Force.
According to Yoshiaki Inose, the sound driver does not have a name.
The driver was first used in Mighty Bomb Jack for the NES. Tsukasa Masuko and Michiharu Hasuya used the driver to create music and sound effects for the game. Both would later go on to program their own sound drivers. The last game to use the driver was Tsuppari Oozumou, which would end the driver's short lifespan of a little over a year.
The driver outputs to the RP2A03 only, and doesn't take advantage of the DPCM channel or any Famicom expansion sound.

The lowest note in the driver unusually starts at D#1 and works its way up to the 8th octave. A G-8 is the highest note heard in the driver (from Chester Field), so it is unknown if the driver actually goes higher than that, as the ROMs the driver is used in only displays D#1 to D-2. An algorithm is used to divide each frequency by 2 to achieve higher octaves.
