Pokémon Yellow Legacy walkthrough
12 parts, one per checkpoint Pokémon Yellow Legacy’s own documentation defines: the areas each one opens, the wild Pokémon and trainers in them, and the fight at the end of it. Everything here is read off the game’s own files, so anything it doesn’t state isn’t claimed.
