Kanto Route 9/Differences among generations/Generations I and III

Only a few cosmetic changes are present between Generations I and III. The normal tree on the side of the -able in the west of the route is changed to a fence and the same kind of tree south of the nearly tall grass is changed to a rock. Some hills are bigger, and all of them are made taller in FireRed and LeafGreen, adding another hill above. Also, the flowers in the west entrance are replaced by trees.
