The ability to reset a Pokmon SoulSilver game to its initial state is achieved through a specific button combination at the title screen. This process effectively removes all progress, allowing for a fresh start or to facilitate a new player experience on the same cartridge.
The necessity for this function arises from the desire to replay the game without any pre-existing progress interfering. This can be beneficial for individuals who wish to experience the narrative from the beginning, experiment with different team compositions, or simply start over after losing interest in a previous save. Historically, this option provides a mechanism for users to share game cartridges amongst themselves.
