I doubt it was even very far in development. All screenshots of Biohazard 1.5 were from the PlayStation version, and it is most likely that Capcom would have only really begun with the Saturn version once the PS1-version was about finished.
I don´t believe any bootleg of the Saturn-port was sold in this universe, and I doubt there even was anything close to playable on the Saturn on Capcom´s very own HDD.
