Unlock Everything
     Start  the  game.  At  the Main Menu, choose "New Game". Select a
slot for your new profile. Enter TUNGHA as the profile name. This will
create  a  new profile called "CHEAT" which will be saved on your hard
drive. The profile has all of the game content unlocked!

     This  gives  access  to each of the 4 Chapters, the 4 Missions in
each  Chapter,  all  16  Challenges, and all 7 Aircraft. Note that the
previous  unlocker  released  for  this  game  only gave access to *3*
Aircraft.
