Aliases Eurhythm

Eurythm (also spelled Eurhythm) was the name of the in-house audio team at Home Data. Unfortunately, because Home Data rarely put credits in their games, the sound team was rarely credited. The name may have been inspired by the English band Eurythmics.

It appears the company broke away from Home Data around the mid 90s. They would end up contributing music to Home Data's rebranding Magical Company, as well as Gaps, a company consisting of former Home Data/Magical Company employees.

Audio Development

Mega Drive

The company used Sega's SMPS for their two Mega Drive games. Shougi no Hoshi uses the Z80 version while Dragon's Eye Plus: Shanghai III uses the 68000 version. Both games were arranged by Junichi Ueda, who converted the composers' songs into the sound engine.

Shougi no Hoshi features music by Novko Hasebe, who, while a member of Home Data, was not a part of their Eurythm sound team. She wrote her music on a Kawai Q-80 sequencer.


Eurythm's sound driver was programmed by Toshiyuki Hirota, based on the credits on Tetra Star. Looking at the data, the music was written in Music Macro Language; two sets of numbers were entered, one for pitch, the second for length. It is possible the composers used letters for notation originally before the conversion into data.

All games that use the driver were only released in Japan.


The company used their own version of the SQ & DBOOT driver by Opus. The Magical Company games seem to use a variant of Kankichi-kun.


Note: This lists all of the games that credit Eurythm, as well as games that credit composers from the Eurythm sound team. For specific composer credits, see each person in the Audio Personnel page.
