Hi
So this one is a bit confusing. Lunar 2 was only released in a “complete collector’s edition” on PS1 - that has the PCID of 45141 (currently it is in Core as 4548).
Now 4548 is “Lunar 2” on Pricecharting as well, but I think that is listing sales that are the discs only (probably filtered by JJ based on “Collector’s Edition not appearing in the listing).
The UPC is 735366010713 (same for both).
So it might be a case of adding a new listing for Lunar 2 (PCID 4548) and adjusting the “Collector’s Edition” to be 45141.
Thank you!
