Pokémon Kanto is map of the Kanto city in Pokemon based on Pokemon Heart Gold / Pokemon Soul Silver.
This is a creative map which means is an open map where you could do what you want with the background of Kanto region like Heart Gold & Soul Silver.
There isn’t any Pokemon in there so if you want to catch one you need to add a different mod.
However there is a few features added to make it feel like a Pokemon world.
1. You may not jump because there’s no jumping in the game
2. Barrier block placed on places where you’re not supposed to go in original game.
Map is playable on 1.8.9 and above
