Sorry for that weird post. I'm on mobile and I guess my finger slipped. My question is that, if I take Pokemon that were Wild Encounter generated from a physical Action Replay all the way back in Emerald be detected as such somewhere in their data if I took those pokemon all the way from Emerald > Pearl > Black 2 > PokeBank > Home > Sword and went online with them? Is there something in their ID that is a dead giveaway? Sorry if this is wrong topic.
