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.

First option is the List which provides various details on all your Pokémon, allowing you to select your Party and the GB and N64 boxes. This gives information including their level, hold item, moves, stats and happiness
Second option is the Pokémon option which allows you to move Pokémon between boxes and allow you to view them, and even re-order their moves
Third option is the Boxes option which allows you to move entire boxes from the GameBoy to the Nintendo 64 and vice versa
Fourth option is Items which allows you to move items between your Pack, your PC and the Nintendo 64 Item boxes; Color Case which can be used between Red/Blue/Yellow and Metal Case which can be used between Gold/Silver/Crystal
Finally is the Mail option which lets you check mail and place it in the mailbox or assign it to a Pokémon.

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 quicktransfer of single Pokémon between games. In addition to this, unlike transferring via boxes, if the Pokémon evolves by trading, they will evolve here.

As you can connect Red/Blue/Yellow to Gold/Silver/Crystal in here, you have the same restrictions to the Time Capsule trading when trading between the two generations of game. As such, you can't trade the following
-Pokémon #152-251
-Any Pokémon with a move which wasn't in Red/Blue/Yellow
-Any Pokémon holding mail
-Eggs

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 has a zoom feature to allow you to look at the Pokémon in full-screen mode. It also has a special part where you can view where in Johto & 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.
