I made this program for studying Japanese, it simply present a question with 4 choices for answer. Just press 1-4 to answer and it continue until you press Escape. This is really just a test version but its working so I decided to add i here... I'm adding questions manually from a book so it take some time, 103 questions for the time being (2012-02-17) (>_<)
This is not a release build so it might not work without downloading some .dll files or so... and you have to set a Japanese font in the command prompt...
It might or might not work for you... Try it at your own risk...
