I have published VGBA-Android 4.2, a new major release of my GameBoy Advance emulator, to the Google Play today:

Starting with this version, the gameplay recorder is permanently on. Click on the "Replay" button (or menu option) to turn the time back any moment you like. I have also fixed the glitches in Mortal Kombat games and added four new games to the Cheatopedia. Have fun!

• Gameplay recording now always enabled. Select "Replay" at any time!
  
• Fixed RLUnCompWRAM() BIOS function, removing glitches from Mortal Kombat games.
  
• Now allowing misaligned source pointers in BIOS uncompression routines.
  
• Made replay play all records to the current recording position.
  
• Made recording pause when replay is on.
  
• Fixed many corner cases in record/replay.
  
• Added Sim City 2000 to the Cheatopedia.
  
• Added Star X to the Cheatopedia.
  
• Added Sega Rally Championship to the Cheatopedia.
  
• Added Rock´n´Roll Racing to the Cheatopedia.
