Thank you for viewing. This is a Wonderswan Color, Stein Gray version. [Exterior] All parts have been removed, cleaned, and repainted. The front part has been replaced with a new one. [LCD] The LCD has been replaced with an IPS LCD. You can change the brightness and color by touching the top of the main unit. [Power] Due to the specifications of the Wonderswan Color, there is a problem where it becomes difficult to turn the power on and off over time. This has been converted to a tact switch, so there is no need to worry about that. [Operation] After the replacement, I tested it for several hours, and there were no problems at all. [Notes] The Wonderswan Color will not start unless a game cartridge is inserted. Please have a game cartridge ready when checking the operation. When the battery level is low, the screen will turn monochrome, and the power will not turn on when the battery level is zero. Please rest assured that this is not a malfunction even if the monochrome symptom appears. You can access the main unit settings by pressing the Start button while pressing the power button. You can set the initial text and birthday, etc. To prevent swapping, cancellations are not accepted. I hope it will reach the hands of someone who will cherish it. As a small bonus, I will include one AA battery for testing. Thank you.
