Follow this procedure before trying the following codes. When starting or continuing a game from the title screen, hold R1 + Circle while the CD is being accessed. A black screen with the words "Now Loading" and flying CD's will appear. While the CDs are flying around, you can enter any of the cheat codes on this page.
When the "Secret Disc Loading" screen appears, quickly press Up, Circle, Triangle, Triangle, Triangle, Circle, Triangle, Circle, Triangle. Next press Circle+Triangle twice and hold them (after the second press) until the game begins.
For 10 extra planes, beat all levels and the boss in easy mode, then watch the credits. When the title screen reappears it should say "Extra 010" in the top right corner. Start a new game and go to the VIEW AIRCRAFT screen to see your new planes.
As the game loads, press Right, Circle, Triangle, Triangle, Triangle, Circle, Triangle, Circle, Triangle, Circle + Triangle, then press and hold Circle + Triangle.
Press Up, Left, Down, Right. During loads, you can play a mini game for about six seconds. You control the Ace Combat icon with Left and Circle or L2 and R2. Your goal is to destroy as many of the swarming Stealth Bombers as possible. If you score above 4.7, you'll receive free wingmen. The word "Congratulations" will appear after the mini-game if you've earned this bonus.
To view these classic aircraft as they were originally designed, press Up, Down, Left, Right, Up, Down, Left, Right, R1.
Secret Loading Screen
Hold the R1 and Circle buttons at any point in the game when the standard "bird logo" loading screen is about to appear. If the "bird" screen appears, you're too late-but if you held the buttons down at the right time, you should see a new, black loading screen with little compact discs bouncing around.
While the game is loading, press and hold the R1 and O buttons. Next, when the CDs start flying across the screen, press U, L, D and R. A small character should then pop up in the bottom left-hand side of the screen to kindly tell you that you've accessed the cheat. The next time that the game loads something up, a secret game will appear.
Hold R1 and press Start ten times.
