Godzilla (Game Boy) 1990 japan

This is the Japanese verison of the Godzilla game boy game. Basicly the same as the one from my other item here http://www.collectorsweekly.com/stories/65446-godzilla-gamboy

There are a few differences in Japanese version when compared to the International versions:

Godzilla moves faster in the Japanese version, with his speed having been decreased in the International versions.
When fighting Hedorah, the player can punch him, instead of pushing him back and stunning him.
King Ghidorah can actually be taken out in the Japanese version, not in the International versions, where he is invincible.
The monsters graphics are different from the International versions.
There is a two-player mode that does not appear in the International versions.
