Pokémon Brown is a ROM hack of Pokémon Red, created in 2004 by Koolboyman. The game takes place in a new region, Rijon, which is south of Johto. The first 151 Pokémon in the Rijon Pokédex are the same as those in the Kanto Dex. In the 2009 remake, the Dex was expanded to 224 Pokémon, and the 2014 remake added Sylveon.
