>In Black 2 and White 2, this route no longer exists and the Badge Check Gates have been relocated.
Oddly enough, if the player uses a cheating device to access this route in Pokémon Black 2 and Pokémon White 2, it only leads to a bunch of trees. However, if the game is reverse-engineered, the entire route is accessible, minus scripts, wild Pokémon data and buildings. In both areas, Route 6's theme plays instead of the regular Route 10 theme.
