I updated iNES-Android to version 4.3.4 today. This release fixes sound which has been malfunctioning for some users. Crackling and buzzing noises should be gone now. The new "Reset All Settings" option lets you return iNES to its pristine state without reinstalling. Finally, if you are using a gamepad with iNES, pressing the right shoulder button will now open the context menu in the File Selector.

• Fixed sound channels not being restored properly.
  
• Added "General | Reset All Settings" option.
  
• Pressing BUTTON_R1 now invokes File Selector context menu.
