I have confirmed that the game works without issue up to the title screen. The battery inside the cartridge may be dead, so I recommend replacing it. You won't be able to save if the battery is dead. It's not a difficult task, as you only need to replace the button battery. This is just my subjective assessment, so please refer to the photos for a more detailed evaluation. To avoid any issues, please refrain from purchasing if you are overly concerned about the condition. I have taken great care to photograph the item to show its condition, but if there's anything unclear, please feel free to ask in the comments.
