Aqua Blue Game Boy Color, model CGB-001, battery-powered. Body only! Operation confirmed. All buttons, including the cross key and AB buttons, responded! Sound sometimes worked and sometimes didn't, depending on the volume. I played games for about 30 minutes, and there was only occasional noise in the sound, so I could play without any problems. The battery cover on the back is missing. Price reduction within reasonable limits is possible. - Model: CGB-001 - Color: Aqua Blue - Country of Manufacture: China - Power Supply: Battery-powered Thank you for viewing.
