X-Change 3 is listed with the same barcode as Jewel Knights: Crusaders, 6 52823 20632 1. Is that correct?

Gamefaqs has a picture of the Jewel Knights cover but I can't find a picture of X-Change 3.

Yep it's correct.. You can see here also: http://www.amazon.co.uk/X-Change-Bishou … B008131FIE ASIN decodes to 0652823206321.

http://redump.org/disc/34295/ and http://redump.org/disc/37284/ are also confirmed to have identical barcodes
