I was getting bored with GH3 for awhile, and then i had the bright idea to look up cheats on the internet.Heres what I found out:Hyperspeed level 5+no fail +unlock all songs=Your friends will think youre an alien.
If color letters are in () you need to hold these at the same time and strum i.e. (ry)if not just hold it and strum once
Enter these in the options menu.No fail doesnt work in solo career mode so you have to use it in quick play. After Hyperspeed is activated highlight it and press the green button until the number next to it says 5. All songs will not show up in the cheats screen but you will get a message that its on.
