I did the questions but i get mystery gift on Pokemon diamond?

Mystery Gift, also called Wonder Gift or Mystery Mail in some localized versions, is a feature in Pokémon Diamond and Pokémon Pearl. It allows the player to receive Pokémon, items or other gifts from Nintendo by connecting to the internet. If the player has a Nintendo DS peripheral device called the Wi-Fi USB Connector or a Nintendo Wi-Fi USB Adapter, they can connect their game to the internet and retrieve Mystery Gift data from Nintendo over Wi-Fi. When the player connects to the internet, they can choose to receive a single mystery gift or multiple mystery gifts. Depending on the version of the game, the player can receive a mystery gift once per day.

To receive a mystery gift, the player must first connect to the internet and then launch the game. From the main menu, the player must select the Mystery Gift option. This option is located in the main menu, along with other options such as Starting a New Game, Continuing a Game, and Options.

Once the player has selected the Mystery Gift option, they will be prompted to select the type of mystery gift they would like to receive. They can choose to receive a single mystery gift or multiple mystery gifts. If they choose to receive a single mystery gift, they will be given a list of available mystery gifts. They can choose to receive a gift from this list or they can cancel the process and return to the main menu.

If the player chooses to receive multiple mystery gifts, they will be prompted to select the number of mystery gifts they would like to receive. They can choose to receive one, two, three, four or all of the available mystery gifts. Once they have selected the number of mystery gifts, they will be given a list of available mystery gifts. They can choose to receive a gift from this list or they can cancel the process and return to the main menu.

Once the player has selected the mystery gift they would like to receive, they will be prompted to confirm their selection. If they confirm their selection, the mystery gift will be transferred to the player's game. The player will then be given a message confirming that the gift has been received. The gift will then be available in the player's game.
