Atari Jaguar emulator for Microsoft XBOX has been updated. Changes:
- Speed improvement, using an optimized library. Some games work faster, and other games have better audio now.
- Rayman works with sound now, and it starts faster due to a BIOS boost trick.
- Other games run better than previous version. Pitfall is a good example. Other games like Double Dragon 5, Cannon Fodder, Evolution-Dino Dudes or Worms, work near perfect now. This is due to the optimized library trick.
- The GUI has a few improvements: roms are sorted by name, and you can use the triggers to advance quickly by the rom list.
