Pokémon Red, Green, Blue, and Yellow The Virtual Console releases of the core series Generation I games are all able to use the Nintendo 3DS local wireless communication to trade and battle, or trade with the Virtual Console Generation II games via Time Capsule, simulating the function of the Game Boy Game Link Cable. The process is done through the Virtual Console menu on the lower screen, with which players can establish connections through a hosting system.
These releases are also compatible with the Poké Transporter, allowing one-way transfer of Pokémon in the player's first Box to Pokémon Bank, where the Pokémon can then be withdrawn by Pokémon Sun and Moon, Pokémon Ultra Sun and Ultra Moon or sent to the upcoming Pokémon HOME. From Pokémon HOME, they can be withdrawn in a Generation VIII game.
