I'm sorry. :/
You could give gamedigga68@gmail.com a try if desparate. I got that contact from Mike (
http://www.arcade-gear.com/, based in Japan, I got my Parodius games from them) when I was searching for some Japanese PS3 accessory that they didn't had in stock.
I hadn't dealt with gamedigga68 yet, but he was very friendly and helpful when we exchanged e-mails.
And Mike from Arcade-gear is just awesome to deal with, so I'd put some trust in his recommendations.
Sending Mike an e-mail as well couldn't hurt, their prices were fair back then in 2013 when they still had their business running, and the condition of the games were unmatched, I don't know any better seller of used games than him. From what I can remember, the Saturn games were priced cheaper than the PS1 ports of Parodius.
