It's also possible that they just did this for internal reasons or maybe the distributor and not Sega was required to put their own unique manufacturer number and UPC on there in line with their own sequencing plan.

Here is the link if anyone is really curious:

Yeah. I was working on a program a few years ago with publishers and a high profile company that handles their data. The program was scrapped because of all the issues with regional UPC matching.
