While only Daisuke Matsuoka is explicitly credited in-game with writing music, the game's website originally stated that the game had "an atmospheric remastered soundtrack arranged by veteran Metroid composers Kenji Yamamoto and Minako Hamano." Three songs are credited to Kenji Yamamoto in the CD-Text of the European version of SAMUS ARCHIVES, although since they're all reprises of songs originally composed by Yamamoto, it's possible he's credited only for the original composition and not arrangement.
