Its a common problem to most GB/GBC games. The battery just stops. I myself dugged up some of my old GB/GBC games I bought when they game out! I was aware of this problem so I was curious if it still worked. I didnt expected it to work after 13 years and 9 Years respectively. But they did work! The games I'm referrig to are Pokémon Yellow and Crystal. Can I be one of the few lucky ones whos game still works? Tell me your story!
