When the Infra-Red Communications Ports of two Game Boy Color systems with the game are connected, each player will receive a random card. A player cannot Card Pop! with the same partner save file again until both players have used the feature with so many others that their partner's ID is overwritten in both save files. If the save file is deleted, all Card Pop! data is deleted, so whether a new save file can Card Pop! with another game's save file is unaffected by the players the previous save file performed Card Pop! with.
Card Pop! cannot be performed between Pokémon Trading Card Game and Pokémon Card GB2: Here Comes Team GR!. Attempting to do so can result in glitches such as a game freeze or a loss of save data in Pokémon Trading Card Game.
