Recently a Preproduction build of Merlin's Apprentice emerged and was dumped by Dopply. Since the disc is a single-data track and Dopply dumped with our recommended "easy" dumping method, Redump.org was able to classify the disc as "properly dumped" and included in it's romset .dat.
The Redump entry can be seen here. Among the data, you will notice the "Rings" section. Ring codes are little numbers are letter on the data side of the disc near the hole. Redump retains these as they are integral information, often pertaining to the build version of the game.
We're always looking out for proper dumps of preproduction discs especially as they often have unique build qualities. For learning how to dump single track CD-i discs, see our dumping guide, and visit the Discord for questions.
