It's typically considered that the canon games are undoubtedly: Blue, Crystal, Emerald, and Platinum.
Third games are the canon games, though some may argue Yellow is canon (I doubt it myself). But what about the other installments? What about the spinoffs? Heartgold or Soulsilver? Firered or Leafgreen? Black or White?
For the FRLG one I suppose you can assume the "canon" game is nonexistent - in canon the games are mixed together. But what about the other three?
