I know it's not the same, but I thought it might work. Also, it can get pretty damn close if you plug in one of those Saturn like pads, that's how I played throug hthe translated trilogy.
I really don't know how else to help unfortunately. You could try downloading an ISO or something and burning it if you have a modded Saturn, but sounds like the disc just doesn't work. I would try to get a refund through eBay.
