Thank you for viewing. GAMEBOY ADVANCE SP Blue Color 【No Battery】 I used a spare battery to actually play games and confirmed the operation. In my subjective opinion, there seem to be no problems with the operation, such as the backlight, volume, and button presses. The battery has deteriorated due to the passage of time, so this item is listed as 【No Battery】. It seems that the power is difficult to turn on due to long-term storage. It turns on after repeated ON/OFF cycles. (It's easier to turn on if you turn it slightly towards OFF after turning it ON. The contact may be bad.) Once it turns on, it didn't turn off during gameplay. (Please note that the box, instruction manual, test play software, battery, and power adapter are not included.) The main unit has signs of wear and tear, such as scratches and dirt, due to use and storage. Please understand that this is an old item.
