Matrimele AES ...insert seems a little small ..

I got my AES Matrimele cart today .

I have the Japanese version and the insert seems very small and leaves a lot of gap on the borders .

I am not sure if all versions are like this but it just seemed odd to me .
if anyone has the Japanese version that they can compare with mine please let me know .

The game is AMAZING though and everyone was right on the money when they said it has a fantastic soundtrack .

I mean it has VOCALS in every stage I have played so far , and the background reacts to the music wich is just a great innovation for a fighter .

My US insert is perfect.

My US insert is perfect as well.

are the Japanese versions and the us versions printed at the same factory ?
