Kanto Route 9/Differences among generations/Generation IV

Many changes are made in this route. The cuttable tree is removed, the tall grass in the west side is slightly moved to the south, the shape of the same grass is also different, the ledge north of the signpost is removed, as a new ledge is added near the center grass, and a hill is added to the route to give it a more in-depth feel. South of the east tall grass, a new fence with four cuttable trees is added replacing the ledge north of the Poké Center, one of these trees not being necessary to pass through the grass. Like in Gold, Silver and Crystal, the corner between it and Route 10 belonged to this route; however, this time the Rock Tunnel entrance is not placed in the route.

For decorative purposes, rocks are added in some hills, as are the flowers near the Pokémon Center and two more hills in the east river. This river is not a dead end to the north like in previous generations; this time the water goes north, but it's still impossible to advance due to rocks blocking the way. The west-to-east part of the river is significantly shortened. Also, the trees in the west entrance are replaced by an extension of the south hill. The fence with the trees mentioned above is very similar to the tree barricade between the Pokémon Center and the Rock Tunnel in Route 10 in Generations and.
