I recently found and bought some SNES cartridges. On the back of each cartridge is a white printed label stating "Property of Square Soft Inc. Product Development" and a barcode with a number. For example, the copy of Final Fantasy Mystic Quest is number 294. In addition, another label is on the back (partially covering the Square Soft label) stating "Property of Crave Entertainment , Inc."

Anything significant with these cartridges? I was just wondering if anybody could explain the history of the labels? Were these cartridges sent to by Square Soft to Crave for some kind of test play? I was just curious
