If it isn't too much trouble, could you upload a version compatible with the Japanese version of the game?

I’ve uploaded a Japanese version! I’ve tested it with version 1.2.1 of the game (the latest available), so that’s the only one I can guarantee it works with. I’ve also adapted the text a little so that some track names and credit lines are in Japanese instead of using romanizations, but some English still remains (I don’t actually know any Japanese). Please let me know if it works or if you find any errors!
