Yo guys! This is (IMO) the best romhack for Pokémon on Game Boy Color. It's super epic in scale with 6 regions and 20 Gym Badges (and everything else mentioned in the features) One of the coolest things is being able to control and play as your Pokémon in interesting puzzle and exploration segments. It's also a loose sequel to Pokémon Brown (also by Koolboyman) since it features the same regions. The original version by Koolboyman was hit with a Cease and Desist by Nintendo and he had to quit development on it. RainbowDevs then later picked it up and finished it and added even more content. Since this game was once targeted by Nintendo I made sure that this post will not be added on the CDromance site and thus can only be found here (to help evade Nintendo) If you're like me and a Pokémon nut I think you'll deeply enjoy this massive romhack. It was just wrong for it not to be on the Repo.
