The release on the 3DS Virtual Console will take place on January the 26th, 2018. Back when Pokemon transitioned onto the Gameboy Advance system, Pokémon from Gen 1 and Gen 2 cartridges weren't legitimately obtainable (via transfer) due to limitations in the link cable design. This means that Pokémon from all main-series games can be legitimately transferred to the latest games. Today an official announcement was made for a 3DS Virtual Console release of Pokémon Crystal.
