Is my Samurai 3 a Korean version?

I bought a Samurai Spirits 3 cart with instructions (no case) for around $70 + $8 shipping = $78. I was playing it today and was going through the language options and Korean came up. I didn't know that Samurai 3 had a Korean language option. I never saw it in any of the other releases. The game sticker says "Made in Japan" but stickers can always me made up. The cart has two different boards. One is green and the other is white. The game plays like an official SNK release and nothing is missing as far as I know. I just wanted to know if it was a solid release or not. <img src="graemlins/help.gif" border="0" alt="[Help]" />

it is not korean.

all SS3s have options for korean and I think portuguese. After the success of 2, they probably thought they would sell this game out all over the place.
