Sega Saturn repros?

Hey everyone. This is on Facebook marketplace and I had bought some games from this person before, some SNES and Famicom. There were a decent about of repros in the mix. She now has a new listing, and I expect some of the nes and SNES cartridges are repros, but I was curious about the japanese Saturn games in the attached pic? Can they easily be reproduced? There are some bangers in there so would be cool to add to the collection.
