Virtua Fighter 1 (not the sequel) sold 1:1 with the Saturn on launch. Virtua Figher was a NEW IP.
"Sega released the Saturn in Japan on November 22, 1994, at a price of JP¥44,800. Virtua Fighter, a nearly indistinguishable port of the popular arcade game, sold at a nearly one-to-one ratio with the Saturn hardware at launch and was crucial to the system's early success in Japan."
Crazy Taxi was also a 'first entry IP' and still outsold Shenmue. Not to mention the VF port on Saturn was terrible.
