In "Pokemon SoulSilver" for the Nintendo DS, users do not delete a save file through the game's option menu. Instead, it requires pressing a set of buttons at the same time. When this is done during a certain part of the "SoulSilver" opening screen, the save file is deleted. Remember, that means that all Pokemon you captured and all parts of the story completed are lost forever.
Instructions
1
Insert "Pokemon SoulSilver" into the DS.
2
Press the "Power" button.
3
Press "Up," "Select" and "B" when Lugia appears on the screen.
