This is a custom WonderSwan Color with an IPS LCD screen, a new shell, buttons, and glass screen. Brightness and color can be adjusted using the sensor on the top of the unit. The circuit board has been cleaned. All buttons and the speaker have been tested and confirmed to be working. Tactile switches have been installed for the power button, start, and select buttons. These provide a satisfying click when pressed, and resolve the common issue of power button contact failure. The unit may restart repeatedly or the sensor may react on its own when the battery level is low. In such cases, please replace the batteries. For those concerned about the consumption of alkaline batteries, we recommend using AA lithium batteries. Nickel-metal hydride batteries may not provide stable operation due to their lower voltage. A protective vinyl film is applied to the screen, please peel it off yourself. Includes a rear label and the Final Fantasy 1 game cartridge used for testing. Shipping will be via Takkyubin Compact.
