Games highlighted in green are games with confirmed composition. Composition for these games have been confirmed by the composer, or have been directly verified through official sources, such as the game's credits or original soundtrack.
Games highlighted in yellow are games with ambiguous composition. These are games where the composer is confirmed to have worked on the game, but in an ambiguous role, such as being credited along with other people for "sound." The composer may have had a non-composition role in these games, such as creating sound effects.
Games highlighted in red are games with unconfirmed composition. These games have been compiled from unofficial sources of composition credits, such as GMCL, MobyGames, or emulated audio sites. While these sites are generally trustworthy, they may not necessarily describe the composer's true role in the game accurately. As such, the composer may not have actually composed any music for these games, or there maybe have been co-composers not mentioned here.
Uncolored games are those where the composer did not compose any music for the game, but did arrange music that appeared in the game.
Special thanks to Jeriaska and Robert Chrystian for confirming some of the details here through correspondence with Iwatsuki and allowing me to share the information.
