This is a set of four karaoke cartridges released by TAKARA. These cartridges are designed to be inserted into a dedicated karaoke machine for enjoyment. Please refer to the photos above for the song list. *Due to the lighting, the photos are not very clear, so please search for "globe" to see the song list. It also has a scoring function. Enjoy and liven up the New Year, family gatherings, and get-togethers with friends. I apologize, but I am unable to confirm the operation as I do not have the main unit. Thank you for looking.
