Pokémon Emerald Plus is a hack of Emerald that seeks to touch up some of the game while preserving the original feel. This include buffing weaker Pokémon, adding buffs that came from future generations, and tweaking a handful of Trainers. Certain Pokémon have gotten type changes, their availability altered, and a small group of older Pokémon have been added to flesh out the region a bit more.
