I have published MasterGear-Android 2.8.12 - a new version of my Sega MasterSystem and GameGear emulator:

In this release, I have added support for x86-based Android devices and made a few UI fixes. As a side result, MasterGear should now run on desktop Android emulators (AndroVM, Genymotion, Bluestacks, etc).

• Added support for Android devices based on Intel x86 CPUs.
  
• Now properly building shared library for each architecture.
  
• Added new-styled action bar, consistent with toolbar.
  
• Added proper icon for the parent directory ("..") entry.
  
• Added DropBox application icons.
