i'm going to leave this topic open just in case, but I can tell you right now that the Pixelmon mod for Minecraft has absolutely no relation, mechanics-wise, with the real handheld games, so any information we might give about the games we know will probably not apply.
Also remember that we're a Pokémon forum, not a Minecraft one. To get your questions answered, I very much recommend you find a forum dedicated to Pixelmon or Minecraft and ask there - you're much more likely to get a useful response.
