I want to hijack this..
Guitar fun notes are off,, slow. They get farther off the longer the song..
Is there a way to fix this?
I thought it was my sd maybe being slow,, tried a few others with the same slow scrolling notes..
The whole point of the game is to be IN RHYTHM. I am using a pack i found from a torrent for guitar fun 3.. 2g download.

Thanks
