I'd be doubtful this ever comes out outside of Japan. The manga and anime haven't been released here as far as I know. The weird thing is my father-in-law will probably want this game because he's been bugging me about this mystical 'conductor' game he insists that he saw
Unpatched ISO confirmed working on NTSC Wii with 3.1U firmware, no updates.
Lemme play this for a moment and will talk about the gameplay and controls.
EDIT: Ok, so far is a nice game, TONS of cutscenes in Japanese -just like the DS game-, but they're kinda funny and I guess it's better if you know the history of the series -or Japanese-, but there's classical music as BGM so I don't have a problem with them.
I've been playing just for like 30-40 minutes,haven't played all the instruments but so far:
Conductor: Maybe I didn't understand what I was supposed to do, ugly experience, hopefully someone will explain the controls later or a guide will be made.
Violin: Nice, really funny. You play moving the wiimote and using the Z button on the nunchuck.
Piano: Fine, you play using the Z and the B buttons and moving both controllers for some notes.
Timpani: Works perfectly, makes you wish a Wii Drums game or a Taiko: Drum Master one.
