I have started this week with the VGB-Android 3.9.15 release, a new version of my GameBoy Color, GameBoy Classic, and Super GameBoy emulator:

I have been fixing hardware emulation bugs over the last couple of weeks. As result, Aerostar, Alfred Chicken, Alien Olympics, Robocop 2, Shadowgate, and many other games work now. I have also added the DI+HALT bug emulation, where CPU will execute the instruction following HALT twice, if interrupts are disabled. Had to make this emulation optional though, as some games (such as Robocop) do not work with it. Finally, the Settings dialog is now tabbed, with the separate tab for hardware emulation options, and some other options (such as fast-fowarding and display orientation) have changed their places.

• Added optional DI+HALT CPU bug emulation.
  
• Now enabling LCD controller on startup (fixed Aerostar, Alfred Chicken, and many others).
  
• Now disabling interrupts on startup (fixed Robocop 2, Shadowgate, and many others).
  
• Now clearing scratch RAM after reset.
  
• Settings are now tabbed, for easier navigation.
  
• Added Emulation section to the Settings.
  
• Moved some options from Input and Video sections to General.
  
• Reordered Settings by importance.
  
• Added Antz and Antz Racing to the Cheatopedia.
  
• Added Armada FX Racers to the Cheatopedia.
  
• Added Animaniacs to the Cheatopedia.
  
• Added Asterix to the Cheatopedia.
