iNES-Android 3.8.6, a new version of my NES and Famicom emulator, is now available at the Google Play:

Starting with this version, the gameplay recorder is now permanently on. You can jump back in time at any moment, by pressing the "Replay" button or selecting the same menu option. The recorder keeps the last 16 seconds of gameplay. I have also added the auto-fire functionality, enabled the new light UI theme throughout the app, and made many small fixes in the core code, mainly to make replay work flawlessly.

• Gameplay recording now always enabled. Select "Replay" at any time!
  
• Added default mappings for generic joystick buttons #1..#10.
  
• Added configurable auto-fire function (see "Auto Fire Settings" option).
  
• Added new "light" theme throughout the app (see "Light UI Theme" option).
  
• Added precise timing counters to the saved state.
  
• Made replay play all records to the current recording position.
  
• Made recording pause when replay is on.
  
• Fixed many corner cases in record/replay.
