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.

Actually to make it work you need to do some save copying. Here is YouTube video showing whole process https://www.youtube.com/watch?v=PATPOwNo6Js

PS: The game gives an error on loading level, so for me it is not working.
