The revelation arrived on social media as Koshiro marked the game’s anniversary, drawing fresh attention to the late-1990s RPG that remains a sought-after title among collectors.
Terranigma was developed by Quintet and published by Enix for the Super Nintendo / SNES platform in the mid-1990s and was released only in Japan and PAL territories.
The game’s limited regional availability and strong reputation for storytelling and design have made it a standout of the Super Nintendo library and a frequent subject of retro gaming discussion.
In a social post highlighted by fans, Koshiro said the anniversary reminded him that he composed the theme for the in-game area 'Beruga’s Laboratory.' He added that the piece had been entirely wiped from his memory and expressed that he was honored to be counted among Terranigma’s composers.
Rewritten for clarity: Koshiro explained that the anniversary jogged his memory of composing the Beruga’s Laboratory theme, which he had forgotten, and that he felt honored to have contributed to the game’s soundtrack.
Koshiro’s career spans landmark projects across multiple systems, and his work on Streets of Rage, ActRaiser, Castlevania-related scores and entries in the Etrian Odyssey series has cemented his status in game music.
More recently, Koshiro has been working on Earthion, a new shoot-’em-up for the Sega Genesis / Mega Drive, which developers have indicated is expected to arrive early this year.
Fans interested in hearing the rediscovered Terranigma piece can find Koshiro’s post and shared audio clips via his official channels.
Terranigma’s enduring reputation continues to drive interest in the SNES roster, and many retro titles gain new listeners through platforms such as Nintendo Switch Online and other digital re-release services available on stores like the Nintendo eShop.
This reminder from Koshiro not only spotlights a single forgotten track but also underscores how pivotal composers remain to a game’s long-term legacy, particularly for beloved developers like Quintet and publishers such as Enix who helped shape the Super Nintendo era.
