Maybe they mean "emulating" as what's known in common parlor, rather than the specific computer science meaning. "Emulating" is a word that existed before computers, meaning just trying to "match" something by imitation. By that definition, it is trying to emulate the experience of Pokemon Emerald, albeit in text and kind of crappy.
