The power turns on, but sometimes the screen doesn't display. No battery cover. Contact is poor, but it works when reinserted, but the screen is dark, so it's being sold as junk. Dry cell batteries are not included. No returns. I was able to confirm the buttons and adjust the volume when the game was working. I'm listing it as junk. - Model: Game Boy Advance - Color: Clear Purple - Battery Type: AA batteries - Serial Number: AJ13633714 Thank you for viewing.
