This morning, I have released VGB-Android 4.2.2, a new version of my GameBoy Color and GameBoy Classic emulator:

This release fixes some remaining problems when using Kitkat SD cards: Cheatopedia, in-game saves, and IPS patches should all work now. For Moga and other analog gamepad users, I have added a way to control analog sticks sensitivity. There have also been a few fixes to the recent File Selector bugs, and the Settings are now accessible directly from the File Selector. See the complete list of changes below.

• Fixed Cheatopedia on Kitkat, when running games from SD card.
  
• Fixed loading .SAV, .IPS, and .PAL files on Kitkat.
  
• Added "Analog Joystick Blind Radius" setting for Moga and other analog joysticks.
  
• Added "Show File Selector Toolbar" option to the File Selector.
  
• Added "Settings" menu option to the File Selector.
  
• Fixed File Selector crash, when deleting a file.
  
• Fixed auxillary files display in the File Selector.
