• Party it up all school-year long with the High School Musical cast in High School Musical 3: Senior Year for the Nintendo DS. This third entry in the Nintendo DS game series carries the torch of the first two and keeps the fun and upbeat spirit of the "High School Musical" series alive by continuing to match the quality of its film counterpart. You can use cheats to help you out in the game; most of these can be unlocked in the DGamer system of your Nintendo DS. All you need to do is complete the tasks listed for every song or achievement in order to unlock them.
  
  

Unlock "Go My Own Way"

• Complete every song and quiz in the game. This is quite simple: you're basically completing every single task in the entire game. Once finished, go into the DGamer section on your Nintendo DS and this song will be available.
  
  

Unlock "Work This Out"

• Obtain signatures from all of the Wildcat team members. "Work This Out" will then appear in the DGamer section.
  
  

Unlock "Bet on It"
