The Sega Mark III was released in Japan on October 20, 1985 at [[Japanese yen|¥]]15,000.<ref name="MK3">{{cite web|title=Sega Mark III|website=Sega Hard Encyclopedia|publisher=[[Sega|Sega Corporation]]|language=ja|url=https://www.sega.jp/history/hard/segamark3/index.html|access-date=February 13, 2025|url-status=live|archive-url=https://web.archive.org/web/20180712025929/https://sega.jp/history/hard/segamark3/|archive-date=July 12, 2018}}</ref> Though its hardware was more powerful than the Famicom, the Mark III was not successful on launch. Problems arose from Nintendo's licensing practices with third-party developers, whereby Nintendo required that games for the Famicom not be published on other consoles. Sega developed its own games and obtained the rights to [[Porting|port]] games from other developers, but they did not sell well.<ref name="Retroinspection" />
