The next fMSX-Android 3.9.4 release is out. In this release, I am trying to address the problem reported by some Bluetooth keyboard users who find most of their keys unresponsive. If you are stuck with such a keyboard, try enabling the "Input | Ignore Fake KeyUp Events" option and see if it helps.

I have also replaced the Layout Editor with the all new Virtual Joystick Editor. The new editor lets you independently resize buttons, shows their labels and the screen edges every button sticks to. Finally, the Assign Keys screen now shows current key assignments for each button.

• Use "Input | Ignore Fake KeyUp Events" if your keyboard doesn´t work!
  
• Now showing current key assignments in "Assign Keys".
  
• Replaced "Edit Layout" option with "Edit Virtual Joystick".
  
• Buttons can be individually resized in Joystick Editor.
  
• Added scale, shape, and transparency options to Joystick Editor.
  
• Added gravity indication with dotted lines to Joystick Editor.
  
• Added button labels to Joystick Editor.
  
• Removed separate joystick size, shape, and opacity settings.
  
• Reordered items in the "Input" tab.
