Using Nintendo WFC for Mystery Gift in Pokémon Diamond: Impossible

Impossible. Nintendo WFC (Wireless Friend Connection) was discontinued in 2014. Original DS hardware can no longer connect for online features like Mystery Gift.

Alternatives

• Physical Event Cartridge: If you have a Mystery Gift distribution cart, insert it and claim via in-game menu.
• Emulators: PC emulators (e.g., DeSmuME, melonDS) may support Mystery Gift with correct event ROMs.
• Online Trading: Trade with other players in communities for event Pokémon.

Caution: Emulators and online trades carry risks (corrupted files, scams). Use trusted sources only.
