I'm selling a fully functional Pokéwalker! I've replaced the battery and confirmed that it works! If you want to play HeartGold and SoulSilver again, this is for you! About the product: * I bought it on the release date and played with it for about a year before storing it at home. * I replaced the battery on January 3, 2025, and it works. * Data remains on the device. * I cannot initialize it, so please do so at your own risk if you wish to. Please understand that this is a used item and has been stored for quite some time. Let's go back to those days, shall we?
