Nintendo launched Pokémon Home on mobile and Nintendo Switch last week, revolutionizing the way in which trainers store their Pokémon. It allows players of all Pokémon games to store their Pokémon all in one place, and even transfer them between games. With a little bit of careful finagling, it’s even possible to transfer Pokémon caught on Game Boy Advance titles into Pokémon Home. There are a fair few steps if players want to make that happen, though.
