Famicom Rocky Theme

This is a Karaoke cartridge for the theme song of the Japanese anime, "Famicom Rocky". The cartridges were sold on GameImpact.info starting in 2021 to celebrate the 7th anniversary of the website. The first cartridges sold were signed by the creator of the Famicom Rocky manga, Motoyuki Asai. Future cartridges are no different, but they don't have the signature.
