Yes, my point, if the answer is that there is no way this works without every disc being different.

It was not possible to manufacture at the time at scale.

It's still not possible. You would need to make a unique master for every individual unit.

You'd use CD-R of course.

		With CD-Rs it was already possible in the mid '90s, if we're talking mass production. CD-Rs are a little more expensive to produce, but not much more so. A slight concern is that readers of the time might not have been able to read the discs, because CD-Rs are not quite as reflective as CD-ROMs.
