U.S. Sonic with UPC sells for $981.33

[understatement]

In the case of the SMS, I think they are. I'm surprised I still have this info on my PC but I saved it from when someone mentioned it years ago.

European boxes UPCs start with 4974365
American boxes UPCs start with 010086
Canadian boxes UPCs start with 069044

Yea, I just checked this and this rule is applied on most all (the only time it differed was when SEGA worked with another company) official SEGA releases to this day just checked my House of the Dead Overkill for Wii. So now that seems like some concrete evidence that a SMS Sonic with a UPC starting with 010086 is a U.S. release.
