Ask a Key fan!

I recently acquired Kanon ~Aso BD~, and I have a couple questions for those who also own the game.

First, does the game contain voices? From what little information I found on the game, I speculated that either the voices are different or they don’t exist at all. I would like to know which of these cases is actually true.

Second, if you look here, my copy reads ‘Ver. 1.01’. What does this mean exactly? Is there a ‘Ver. 1.00’ anywhere, and if so, what are the differences between the two? I suspect it’s only bugfixes, but I suppose it wouldn’t hurt to know.
