This new release should greatly improve the audio quality. I am continuing to make the audio better though, so expect more audio improvements in the upcoming versions. I have also fixed a nasty typo that sometimes made emulator crash after running a few games and added a bunch of new menu options to the File Selector and the Cheatopedia. Finally, quitting the emulator is now achieved by pressing the BACK key twice, to avoid accidental exits. You can restore the original behavior by disabling "Press BACK Twice to Quit" in the Settings.

• Fixed square wave audio frequency sweep (Dragon Warrior 4 and other games).
  
• Partially fixed support for register $4017 (APU frame rate and IRQ).
  
• Fixed a crash in the Record/Replay icon display.
  
• Now exiting emulation when user presses BACK twice (not once as before).
  
• Disable "Press BACK Twice to Quit" setting to restore original behavior.
  
• Added "Quit" menu option for people who cannot find their BACK key.
  
• Added "Completely Delete File" to the File Selector context menu.
  
• Added "Report Non-Working File" to the File Selector context menu.
  
• Added "Report Non-Working Cheat" to the Cheatopedia context menu.
  
• Added multiline cheat entry to the Cheat Editor.
  
• Fixed localized strings in Cheat Editor.
  
• Fixed several bugs in the Record/Replay functionality.
  
• Fixed license verification crash when no network available.
