Radical Red walkthrough

18 parts, one per checkpoint Radical Red’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.

    7 areas

This game's documentation doesn't say where 25 of its 678 fights happen, so those trainers are on no part of this walkthrough; they are all on the Trainers page. It also doesn't say when 7 of its areas open up, so they are listed together in the last part rather than guessed into the story.
