After data mining Pokemon Red and Blue, hackers found something very interesting. In the patch of code where the cities were located, they found an empty slot. There was a city in the middle of nowhere below Celadon City and above Fuchsia City. The only hint of a name was the symbols 0b.
More data mining produced that there was coding for a Pokemon Center, a Pokemart, even what the Pokemart sold.
It is impossible to access 0b. Even using GameShark will not work. Whenever anyone attempts to access 0b the game will freeze.
