Many users reported that after the last VGBA update, some Cheatopedia cheats turned into empty folders. The new VGBA version fixes that and adds a new virtual joystick skin, for those who liked the old circular directional pad.

ALL CHANGES:

• Fixed Cheatopedia bug that made some cheats turn into folders.
  
• Added joystick skin with round directional pad.
  
• Moved invisible and wireframe joystick settings to "Virtual Joystick Shape".
  
• Added more options under "Virtual Joystick Opacity".
