Hint: Skip Difficult Parts
Here’s a great way to skip difficult parts of songs that you can’t keep up with. What’s more, your note streak and rock meter level will be unaffected. During a difficult moment you want to skip, close the lid of the DS. This will pause your game. Open the lid, and the game will continue, but the notes that were on the screen will disappear as the song proceeds. This gives you a chance to catch back up with the song. You can use this to your advantage to skip undesirable sections of songs you’re having difficulty with!

Hint: Faster Scrolling Credits
If you choose the Credits option from the main menu, you can make them scroll faster and faster by strumming across the screen with your pick.
