The updated VGBA-Android 4.2.5, a new version of my GameBoy Advance emulator, is now online:

This version adds an option that forces VGBA to emulate either 6bit or 14bit EEPROM, used for in-game saves. If in-game saves do not work for you in some game, try this option in the Settings. Be aware that changing the EEPROM type also resets your game though. Also added seven new games to the Cheatopedia.

• Added "Choose EEPROM Size" setting to force 6bit or 14bit EEPROM type.
  
• Added Teenage Mutant Ninja Turtles to the Cheatopedia.
  
• Added Teenage Mutant Ninja Turtles 2: Battle Nexus to the Cheatopedia.
  
• Added Yu Yu Hakusho: Tournament Tactics to the Cheatopedia.
  
• Added Yu Yu Hakusho: Spirit Detective to the Cheatopedia.
  
• Added Tekken to the Cheatopedia.
  
• Added Wolfenstein 3D to the Cheatopedia.
  
• Added Wings to the Cheatopedia.
