Michiharu Hasuya (NES Driver)
Michiharu Hasuya is an unofficial name of the sound driver used exclusively by Michiharu Hasuya throughout his NES music career. It appears to be based on the code of Yoshiaki Inose's sound driver. In Golgo 13: Top Secret Episode, Hasuya is credited as a sound programmer, so he most likely made the changes to Inose's driver.
The sound driver has a similar sound to Ken Moore (NES Driver). However, these are two different sound drivers.
The first game to use the driver was Solomon's Key by Tecmo. Hasuya had previously worked with Tsukasa Masuko on Mighty Bomb Jack (NES) using Yoshiaki Inose's sound driver before he programmed his own. The last game to use the driver was Conflict, which was done while Hasuya was working freelance for Vic Tokai. Hasuya was also working at Advance Communication Company and may have programmed their sound driver as well, as their sound driver is also based off of Inose's sound code.
In the later years, Hasuya updated the sound driver and the frequencies were tuned up, so the music sounds approximately a ¼ step up. Hasuya may have done this to accommodate the issue with PAL games in which the music was tuned a half-step down and played a little slower. It could also be because he simply liked how it sounded. ACC's sound engine did the same thing.
The driver outputs to the RP2A03, the NES's sound unit. No expansion sound was ever used, and the DPCM channel was also never used. The triangle channel was used, but rarely.
