Alternative layouts in Konami cartridges

Yes, those are the japanese versions of the games. In the early Konami-MSX days, almost all japenese and european versions had different artwork. From Yie Ar KUNG-FU are two different japanese versions. The one you mentioned, and the european layout, but with japanese text. By the way, in most cases the software/game is exactly the same. The only difference is the cart-label, box and manual.
