63 more areas the same checkpoint opens, each with its own page.
This game's documentation doesn't say where 50 of its 386 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 49 of its areas open up, so they are listed together in the last part rather than guessed into the story.
