This is the Game Boy Color game "Pokemon Gold." The backup battery was replaced with a new one in the spring of 2024. I have played it on an actual Game Boy Color, so it works without any problems. The cartridge has minor scratches and scuffs. The Game Boy Color console used for the operation check in the last image is not included. ● No need to comment before purchasing; direct purchase is welcome. ● It will be shipped via Yu-Packet Post (Yu-Yu Mercari Delivery). ● Due to work, I may be away for 2-3 days, so shipping may be delayed depending on when you purchase.
