I was able to confirm that the power lamp lights up. However, I don't have a Game Boy, so I don't know if it works. I'm including a communication cable! There's also a roll of paper, but it's almost empty! Batteries are not included, and there is no box, so please be aware of that! I don't think there are any noticeable large scratches, but please refrain from purchasing if you are looking for a perfect item, as it has been stored at home. No price reduction ❌
