Kingdom Hearts Birth by Sleep Final Mix

[GigaSkob]

I'm playing the game on the latest version (0.7.6) on windows 7, and I encountered a problem. In Ventus story, you need to beat one song in Ice Cream Beat mini game to progress the story. But, at certain part of the song, the game speeds up (like I pressed a turbo button or something) and it becomes impossible to get enough points to beat it, as it is a rhythm game. Are there any fixes to this? I can't play further without beating that mini game.
