Hiroshi Yamazaki (NES Driver)
Hiroshi Yamazaki (NES Driver) is an unofficial name of the sound driver programmed by Hiroshi Yamazaki.
Music was written first in 6502 assembly and later in MML.
Yamazaki has only been credited in Elysion, but it seems that this sound driver he programmed has been used in other games. All the games on the list have been verified. This driver was mostly used by Kazuo Sawa, who is a freelance composer, this is the reason is that this sound engine can be found in many company's games. Besides, a few other people also used this driver, including Noboru Machida, Kuni Kawachi, Seiji Toda, Toshiko Tasaki and Takeshi Yasuda.
The first game to use Yamazaki's NES driver was Tokoro-san no Mamoru mo Semeru mo. Almost all games that use this driver were released only in Japan, but some games were released in North America and Europe, including Astyanax and The Battle of Olympus. The last game which used this driver was Break Time: The National Pool Tour.
This driver also used in some FDS games, in which the FDS channel was used, but unfortunately, the programmed FDS channel is out of tune from the 2A03. The FDS games include some unlicensed games that also use this driver, but these games do not use the FDS channel.
