Hi guys, I just got my used PS2 from ebay...it is working fine. It is a 30001R but here is my question. Instead of the ordinary white tag serial number, it has a yellow tag with the letters WMR-001. It seems to be in good overall cosmetic and working condition but I have absolutely no idea of what that yellow tag is. Does anybody know? Please help. PS I bought the PS2 from a large company that sells on ebay and they had no clue what the tag is.
