Nintendo Game Boy Color Pokemon Silver With Case I purchased this new at the time and played it, but it has been stored in a dark place for over 20 years. I have confirmed that it works by booting it up on a Game Boy Advance for this listing. The internal battery has been replaced, and I have confirmed that saving is possible. *During the battery replacement, the tool slipped and scratched the back of the cartridge. I will take measures to prevent water damage and shock during shipping.
