Pokemon FireRed and Pokemon LeafGreen on Nintendo Switch are officially compatible with Pokemon HOME, allowing players to transfer Pokémon into the broader ecosystem. The update makes it easier to bring classic Kanto partners forward into newer titles, expanding long term collection options. With HOME support in place, Trainers can preserve Pokémon caught in these retro adventures and integrate them into modern teams. It is another step toward tighter connectivity across generations on Switch.
