I have just published VGBA-Android 4.1.11, a new version of my GameBoy Advance emulator:

The main addition is configurable fast-forward speed, requested by many users. You will find this new option in the Settings, next to "Persistent Fast-Forwarding" option. I have also added three more games to the Cheatopedia.

• Added fast-forward speed setting (x2, x4, x8, or maximal).
  
• Added Contra Advance: The Alien Wars EX to the Cheatopedia.
  
• Added Crazy Taxi: Catch a Ride to the Cheatopedia.
  
• Added Desert Strike Advance to the Cheatopedia.
