>>37902885HeartGold and SoulSilver added in features from Crystal, like certain encounter rates, the password show, the extended Ruins of Alph puzzle, as well as adding in new features, like a Safari Zone in a new route, the Battle Frontier, following Pokemon and the shiny leaves, and probably some other things that I can't name right now. There's no reason you can't apply Emerald enhancements to versions in a remake. Even the Hoenn battle tower wouls have been fine as opposed to the Battle Maison just as a change of scenery, but those remakes didn't even honor that. There were good things too, like DexNav and Secret Base enhancements, but it didn't feel like enough.
