BS-X: Sore ha Namae wo Nusumareta Machi no Monogatari (commonly translated as "BS-X: The Town Whose Name Was Stolen") was a requisite system cartridge for the Satellaview that served as both an interactive menu and its own game. The game's hub world, which was noticeably similar to the one featured in EarthBound, featured numerous buildings representing each of the system's services. After creating a custom avatar, players could purchase items from in-game stores, play minigames, see announcements from Nintendo and St.GIGA (the two companies responsible for the Satellaview), and participate in contests. Additionally, the cartridge the game came on provided extra RAM for the Super Famicom, increasing its hardware performance.
