Here's why:
* The Pokéwalker is integrated with the games: The Pokéwalker is a peripheral device that interacts directly with the game cartridge. It's not just a separate device you can turn on and off independently.
* Data transfer: The Pokéwalker acts as a secondary game world, allowing your Pokémon to train and collect items. This data is constantly synced back to your game cartridge.
However, you can effectively disconnect the Pokéwalker from your game by:
* Turning off the device: While the Pokéwalker is physically connected, you can turn it off, preventing data transfer. Your Pokémon will stop training, but the data will remain on the device until you turn it on again.
* Removing the battery: This will stop the Pokéwalker from functioning entirely, but you will lose any unsaved progress.
* Using the game without the Pokéwalker: You can play your HeartGold or SoulSilver game without the Pokéwalker attached. However, you won't be able to access the Pokéwalker features.
Remember, the Pokéwalker is a key part of the HeartGold and SoulSilver experience, so disengaging it will limit gameplay features.
