Make Songs Easier
To songs easier in "Guitar Hero 3" for the PS 2, move the Strum Bar Up and Down before the chord appears and the song begins, until the meter stops going down. When the meter finally stops, it will be in the red section. When the meter begins again, it will be towards the middle of the song. To make "Through the Fire and Flames" easier, pause the game before using Star Power, hold "Select," and then resume the game. This cheat helps you avoid missing many notes, if you are aiming to achieve a five-star score.
