Apparently, two Sega games were released on PS1 in Japan. And other saturn game ports were announced to be worked on, but I don't think those games have been confirmed. A Sonic 1 2.5D remake is rumored to have been planned. http://www.assemblergames.com/forums/showthread.php?46681-SEGA-Saturn-games-for-PlayStation-One Can anyone read this? Might be italian.
