Hatsune Miku Project DIVA Dreamy Theater Extend [NPJB00201]

I really need someone's help on this. I'm testing this game on the newest build the march 22 one, but I can't tell whether the game is actually working or not because well... it's in JAPANESE.

The first picture asked me a question, which it only lets me go on if I say yes to it.

Then on the 2nd pic, what I think is the menu is displayed. Yet I chose every button there is, yet why won't it let me play a rhythm game? If I push a button sometimes it restarts on its own. So is this because of the emulation or something else?

Also attached is the log file. Thanks.
