Kanto Route 1/Differences between generations/Generation IV

Other than graphical updates, the basic layout remains the same as previous generations, but the route is no longer flat, due to hills being added to give feeling of depth to the route. Heading south from Viridian City, a gate has been added between the route and Viridian City, in order for the game to load the different tilesets used between the areas.

The Bitter Berry tree has been changed into a Blk Apricorn tree, which can be found between the two ledges located on the northwestern side of the route. By traveling east, Trainers are able to battle a, and by jumping off the ledge and heading east, another Schoolboy can be challenged, with Pokémon similar to the other Schoolboy in Generation II.

By jumping down the ledge and going through the tall grass, the route soon turns into the clearing. Like in Generation II, the Viridian Poké Mart employee is no longer present and is replaced by a Trainer. However, a photographer is present on Mondays, Tuesdays, and Saturdays who will take a picture of the player and his or her party.

There is a male just south of the photographer, as well as another female, with Pokémon similar to the other Cooltrainer in Generation II. Route 1 makes the "S", turning to the south, then to the east before returning south and west, passing through the third grassy area. The path then juts south, entering another patch before curving to the east then to the south as it enters Pallet Town.
