Wonderswan Worm Light Only - Rare Power-on confirmed with my own Wonderswan. The light sometimes turns off when touching the connector. It's unclear whether the problem is with the main unit or the light itself. Please comment if you have any questions. Please refrain from purchasing if you are concerned about minor scratches, as this is an old item from over 20 years ago. Returns and exchanges are not accepted to prevent trouble and swapping, so please understand!
