I have finally added a realistically looking virtual keyboard to fMSX-Android 3.7, published to Google Play today:

https://play.google.com/store/apps/details?id=com.fms.fmsx.deluxe (full version)
https://play.google.com/store/apps/details?id=com.fms.fmsx (free version)

In this new version, I have also reorganized the menu system and optimized the File Selector for faster and smoother operation. Also, the nag-free fMSX Deluxe now costs only $1.99 (1.99 euros in EU) on Google Play. I doubt that more people will buy it, even at this rather miniscule price, but let us test this theory for a while.

• Added realistically looking virtual MSX keyboard.
  
• Collapsed all advanced menu items into single Advanced submenu.
  
• Made NetPlay a single checkable menu item.
  
• Now only showing File Selector progress dialog for large folders.
  
• Optimized File Selector labels and screenshots for smoother scrolling.
  
• Optimized communications from native code to Java code.
  
• Fixed NetPlay crash when own IP address cannot be detected.

Have fun!
