The current databases of CD-i demonstration and testing discs absolutely do no justice to the wide ranges of discs that have been pressed, but how to improve this?

Next to the white label "CD-i Demonstration discs" (of which we see some fake discs recently) and "Testing Phase" CD-i discs about testing versions (pre-release) - we've also see a different range of demo CD-i discs with a blanc disc appearance and a red "Not for Resale" message on it. Again, most copies that are found on the internet are of the Nintendo CD-i titles, but CD-i member Mini recently posted his collection of these "Not for Resale" discs. They are 'for promotional use only' - just like the white label CD-i discs. It may be these discs were used in a different region: As we see european catalogue numbers on it, these discs may have been used in Europe by Philips Media. On the other hand, we also have seen white label CD-i discs with a european catalogue number. One thing is clear: the current existing databses of CD-i demo discs absolutely do not do justice to the ranges of CD-i demo and testing discs that actually exist. How to improve this?
