In the Dreamcast version, despite having only been released in Japan, the entire English localization is present in the game, even retaining the English title "Puyo Pop Fever", and can be toggled from the Options menu. This hints at a possible Western release of the Dreamcast version that never materialized due to the discontinuation of the console by the time the game was released elsewhere, making it the last Dreamcast game developed by Sonic Team, as well as the last first-party Sega title released on the platform. The Dreamcast version is also the only version of the game to use sprites instead of 3D models.
