First, read about Pokemon Black (not to be confused with the impending Black/White releases) in this post by Tiny Cartridge. It's a longish read by Internet standards, but highly worth your time.
Yes, I know you want to believe this bootleg game exists; I desperately do too. It sounds too brilliant to be real, though. Honestly! The good news is that thanks to a dedicated group of individuals, we don't have to worry about such thoughts.
"Project Creepy Black," a now in-the-works hack of Pokemon FireRed, aims to provide the same meaning and mechanics as those presented in the aforementioned story. More than any other fan project out there, I want this one to actually get finished. Best of luck to you, team.
