So here is something quite unique and insanely rare. The Korean release of Kinnikuman Generations! It uses the cover art of the USA version, which was released there as Galactic Wrestling, but uses the Kinnikumkan name since it was more familiar here. The game itself is actually the English version. Only thing that is Korean is the slip cover and the manual. And in Korea, the system region was NTSC-J.
So technically, this is the only way to play Kinnikuman Generations on a Japanese system in English! Unless you are a filthy pirate that is!
