Sakura Taisen Kinematron Hana-gumi Mail

A piece of Sega Dreamcast software distributed exclusively with Sakura Taisen-branded Dreamcasts which is essentially a glorified emailing service, where the user can send emails with Sakura Taisen imagery. In order for the recipient to see the added features, he/she must also own this disc, otherwise the email will be rendered simply as text (which effectively means the recipient must own a Sakura Taisen Dreamcast). Given the state of the Dreamcast’s online capabilities in the modern age, the disc is largely unusable today.
