I picked up a stack of Genesis carts at a thrift store this morning and didn't notice till later this evening that the box art for Decapattack was different from the copy I already had. The artwork fills more of the front cover, has the standard Genesis logo at the top but has "For use with the Sega Mega Drive Video Entertainment System" in small print at the bottom. The back cover is in multiple languages like a PAL Mega Drive release and the cart is the same as the US release.
Was this just something that Sega did for certain markets? Any info is much appreciated.
