The Battery mod

The battery charges using a USB-C to USB cable. USB-C to USB-C cables are not compatible. This cable should be plugged into a standard 5V USB power source (for example, a phone charger).

When the battery is charging, a red LED lights up on the side of the Game Boy. When the battery is 100% charged, the LED turns off.

When the battery is almost empty, an orange LED lights up on the side of the Game Boy.

There is no need to wait for the battery to be completely charged before unplugging it. Similarly, the battery does not need to be completely discharged before charging it.

If the battery becomes swollen or emits a strange odor, unplug it and remove it, then contact me for a replacement. The battery comes with a 2-year warranty.

The RGB LEDs

To access the settings, press and hold the START + A + B buttons until the LEDs flash:
- START changes the color of the Start and Select buttons
- UP changes the color of the D-pad
- A changes the color of the A and B buttons
- B adjusts the LED brightness

The settings will be saved after 3 seconds of inactivity.
