2 metal slug 3 releases ???

Could someone tell me how to differenciate the 1st and 2nd releases of metal slug 3 japanese cart ???? Thank you!

If I'm correct the first run had a gold warning sticker under the label on the game cartridge, and the last page of the instruction manual manual is different. <img src="graemlins/eye.gif" border="0" alt="[Eye]" />
