I have updated MasterGear-Android to version 3.3 today. Since I have got an ADT-1 AndroidTV box to test on, this version contains many optimizations for AndroidTV and other devices without touchscreens. The gamepad BACK key now exits the emulator, while pressing A+BACK will open the menu. The "Assign Keys" dialog has been redesigned to completely avoid the touchscreen use. I have also updated the banner image and added overscan border on AndroidTV devices

• Removed waveform interpolation for more realistic sound.
  
• Optimized app for AndroidTV, tested on the ADT-1 box.
  
• Added overscan border on AndroidTV devices.
  
• Added hints to the emulator and key mapping dialog.
  
• Fixed crashes on devices with no web browser (e.g. ADT-1).
  
• Replaced AndroidTV banner image.
  
• Enabled gamepad-only emulation interface.
  
• Press BACK on gamepad to exit emulation.
  
• Press MODE or BUTTON_A+BACK to open menu.

• Xperia CIRCLE button now acts as BUTTON_B.
  
• Redesigned key mapping dialog.
  
• Press same key twice to remove it from assignments.
  
• Press same key three times to confirm key mappings.
  
• DPAD_CENTER key no longer confirms key mappings.
