I have released the new version of my GameBoy Advance emulator for Android, VGBA-Android 3.9.56.

The main changes this week are fixes to the BIOS emulation, full support for the standard gamepads in all parts of the app (not just in the games), and support for the iCade joystick accessory. There are a few other changes as well, listed below.

• Fixed in-game saves in Avatar.
  
• Fixed ArcTan2() BIOS function (Mario and Luigi, etc).
  
• Added standard gamepad support to File Selector, Gallery, and Settings.
  
• Added optional iCade joystick support (see Settings).
  
• Added "Show Real Names" menu option to the File Selector (on by default).
  
• Optimized File Selector by not rescanning folder after running emulation.
  
• Added Summon Night and Summon Night 2 to the Cheatopedia.
  
• Added "debug room" cheat for Mother 3.
