Like most Nintendo 3DS games, Pokémon Tretta Lab has got a special feature that is automatically downloaded when your Nintendo 3DS is connected to the internet, using the system's SpotPass.
The Pokémon Tretta Lab Main System utility has got various features which rely upon the data of the Pokémon Tretta pucks. As new sets are released every 2 to 3 months, the game has to be updated in order to be able to both read the pucks, and provide information about them.
In the Type Checker, you have the ability to check the details and bring up dozens of Tretta which you may not have yet obtained or scanned. Also, in Challenge Battle, you face off against various Pokémon from these various sets in order to win.
To opt into the SpotPass notifications, there is an option in the main menu for you to opt in or out of it. Should you opt in, that's all you need to do. When the new data is sent, you will receive a blue SpotPass notification onto the game's icon on the home screen.
