How do you get a gs ball in crystal? - Answers

In the Pokemon Crystal games released for the Gameboy Color only the Japanese version could've received it by going to the Pokemon Communication Center after linking a Mobile Adapter with the games and beating Blue but the Communication Center's wireless services were later disabled. In the Virtual Console version of Crystal all versions can receive the GS Ball the Japanese version needs to go into the Communication Center while other versions have to go into the Goldenrod Pokemon Center however you need to beat Lance before you can get the GS Ball in the Virtual Console version.
