This is a PC Engine GT. It comes with an AC adapter, a TV tuner, and a car adapter. Regarding the main unit, the exterior shows signs of use, but I think it's in relatively good condition. For the power, the AC cord connection seems to be poor, making it difficult to start up, and it turns off if moved around vigorously. I was able to play games. The sound is very faint. It's barely audible. I don't think it's quite junk, but it's an old item and an electrical appliance, so please understand. No claims and no returns, please.
