Pokémon Model Ripping Project

[Muse 2]

Sorry if this isn't the right thread for this question/it's been asked before/this is common knowledge but i was wondering about the naming of the bones on the models, if the names were how they were originally or if they were renamed by a converter of some kind? I'm trying to figure out of Game Freak/Creatures Inc. actually calls things "feelers" on their models or if that's just an exporting thing.
