Hironari Tadokoro' was a Japanese sound designer, programmer and composer. He worked on a few games developed by Marionette, the first of which being Mezase Pachi Pro: Pachiokun. While he was usually only an audio programmer on these games he did compose for a few of them, most notably Phantom Fighter, and was a part of the group of composers who worked on Dr. Chaos (Ponii Ichinen). After the release of Pachio-kun 5, Tadokoro left the game industry.

He also worked at a game company by the name of IDES, producing and providing scenarios for a number of their games, later doing the same at his own company STONE HEADS and freelance later still. He still found time to contribute musically from time to time with his lyrics and compositions showing up on occasion in these games, and even worked on music for the album Maid San Best 2.

He continued to be active until his unfortunate passing on December 8, 2018.

Music Composition


Hironari programmed his own sound driver in 6502 assembly. Music and sound effects were written in Music Macro Language. While he was working on the Pachiokun games, the composers sent cassette tapes to him and he rewrote the music to his sound driver by hand.

According to Tadokoro, there would be revisions made to the driver between each game it was used in, which is why each game that uses the driver sounds different.

As per usual with game developers back in the early days of game development, Hironari used several aliases throughout his career.

In Pachipro Densetsu (MSX), he goes by Keith Jagger and in Pachinko Daisakusen (FC) he is credited as Mick J. Piro. Mick, Keith, and Jagger refers to the Rolling Stones band members Keith Richards and Mick Jagger.

Hironari used "Piro" in many of his aliases. "Piro" may not mean anything in particular, and he only used it because it rhymed with the first half of his given name.
