Kid's Club
White City also features a Kid's Club where players can play minigames involving various Pokémon competing which each other for the best score or best time. Kid's Club features a minigame champion mode where players compete to collect the selected amount of coins and the winner of the game gets to see a display of the Pokémon from the minigames that player won in. If the Nintendo 64 Transfer Pak is attached alongside one of the Game Boy or Game Boy Color Pokémon games and that player wins the minigame champion mode, then the coins that were selected will be distributed to the Coin Case in the respective game.
The club also features a new quiz game where one player can tackle as many questions as they can answer within a certain time limit. The modes Easy, Normal, and Hard determine the type of questions that appear. The quiz game also features a multiplayer mode where players compete to answer questions until one player reaches a score of ten. White City also has a Free Battle arena where players can battle against each other using Pokémon from Generation I and Generation II, and even fight a CPU player.

Professor Oak's lab is only accessible with a Game Boy or Game Boy Color Pokémon game inserted in the Nintendo 64 Transfer Pak. The lab features a PC system much like a Pokémon Center with an easier way to organize, move, and transfer Pokémon. The PC can be used to transfer items and mail as well and even release Pokémon. The PC features a special box called the N64 Box, this being the storage system for Pokémon Stadium 2 and can be used to transfer Pokémon in a different form of trading by dropping off the Pokémon for whichever game the player are sending them to (i.e., Red) and then insert Red in the Transfer Pak and transfer the Pokémon from the N64 Box to one of the PC Boxes in the actual game. The transfer can also be done to the current Pokémon party as long as an available space exists.
Also, a Pokédex is available for viewing much like the original Pokédex, but with more detailed areas with pictures of Pokémon. A trade machine is also here where two Nintendo 64 Transfer Pak holders can trade between each other rather than using link cables. A special case for items called the Metal Case (for Gold and Silver) lets the player drop off items and keep them in the game, and can be used to transfer items to other players, much like Pokémon. The Color Case is for Red, Blue, and Yellow Versions versions only, and can be used like the Metal Case.
