In Pokémon Stadium's predecessor, a variety of features were created to help aid in the organisation of the various Pokémon within your game, allowing you to quickly sort features of your game. Pokémon Stadium continues this, and adds various extra parts to the functionality

Sophisticated PC

GameBoy Game Required: Yes
Saved at the Pokémon Centre: Yes

The Lab PC provides the ability to organise your various boxes, allowing you to send various Pokémon to and from various boxes. In this mode, you can check the basic information of all the Pokémon in your boxes, including moves, stats etc. You can move the Pokémon between the boxes or into a different position in the box and you can release the Pokémon.

In addition to that, this PC comes with 12 special boxes on the Nintendo 64, which allow you to store the Pokémon on the Nintendo 64 game so you can capture more in game. Finally, you also have the ability to store items into the boxes within the game.

Trading Pokémon

GameBoy Game Required: Yes
Saved at the Pokémon Centre: Yes

A feature that the predecessor lacked was the ability to trade Pokémon. If you have two GameBoy games inserted into the Transfer Paks of the controllers, you have the ability to trade between the two games without use of a Link Cable. This allows for some quick transfer of single Pokémon between games. In addition to this, unlike transferring via boxes, if the Pokémon evolves by trading, they will evolve here.

Switching Game

GameBoy Game Required: Yes
Saved at the Pokémon Centre: No

This feature in the Pokémon Lab essentially makes you choose the game you are wanting to utilise in the lab. This can be handy to do quickly in order to transfer boxes between the various games.

Pokédex

GameBoy Game Required: Yes
Saved at the Pokémon Centre: No

This mode allows you to check through your Pokédex. Here, you can see all of the Pokémon in 3D as well as get their Pokédex information. It also has a special part where you can view where in Kanto they can be found, where it also lists the level in which they are found. A toggle can be used to superimpose the map from the game over the image

Receiving Prizes

GameBoy Game Required: Yes
Saved at the Pokémon Centre: Yes

The final feature of the Pokémon Lab is used in conjunction with the other modes. If you do well, you will occassionally earn a Pokémon prize. When you enter the Lab after earning the prize, Professor Oak will entrust the Pokémon to you and get you to place the Pokémon into one of your boxes
