Strategy X cart with a difference

[JingleJoe]

I got a copy of Strategy X a little while ago, it's rather fun, if a little difficult, sometimes I feel like I'm only winning by chance

However I noticed a difference on my cartridge; Instead of Konami it says Gakken at the top of the label! Did Gakken just release the PAL version? Or have I found some rare oddity?

 

P.S. It came with the instructions and I notice there is no manual scan so I'll get that up soon

PAL only.
