Extra Fighters

To gain these extra fighters, play through the game on Easy Mode to the last mission and defeat the Boss. Once the mission is completed and the game is over, the credits will appear on the screen. Sit through this in its entirety until the title Screen appears. You should then have "Extra 10" in the upper-right corner of the screen. Now go through the optons to the plane select and notice there are several more fighters to choose from.

Here are some codes for Ace Combat I got from the Japanese Hyper Playstation
magazine. Before entering each code, you must do step 1.

STEP 1:

When starting/continuing a game from the title screen, hold down
R1 + O while the CD is being accessed. A black screen with the words
"Now Loading" and flying CDs in the background will appear. While the CDs
are flying around, you can enter one of the following codes:


CODE 1: Undecorated planes with original paintjob.
U, D, L, R, U, D, L, R, R1

CODE 2: Undecorated wingman.
Hold R1, press START ten times.

CODE 3: ??
L, R, L, R, D, U, D, U, O, O, T, T, T

CODE 4: Unlimited cash (Unconfirmed)
Hold D, C, T, T, T, C, T, C, T, C + T

CODE 5: Hidden game.
U, L, D, R

During loads, you can play this mini game for about 6 seconds.
You control the Ace Combat icon with L or L2 and O or R2, with the
aim of destroying as many of the swarming Stealth Bombers as possible.
I think if you score above 4.6 points/sec you'll get some special
bonus (not sure about this).


Each time a code is successfully entered, a representative icon will
appear at the bottom left of the flying CD screen.

Have fun!


Tip on playing the extra game: Hold down the O button.  This
will make you spin in small circles.  To move your plane,
release the O button momentarily--while released, you will
fly straight.  Hold the O button down again to resume flying
in circles--a little practice with this method and you'll be
able to move around without crashing on the edge of the
screen.

Also, after i got a score of 4.75 pts/sec, wingmen were free.
(you'll know it because when the hidden game is over, the
word "Congratulations" appears under "Complete")  I'm not
sure of the minimum required score, but i know it's between
4.15 and 4.75--possibly 4.6 pts/sec?

The extra game on the higher missions has little UFOs instead
of stealth bombers, and a little superman-looking character as
well--if you hit him, he speeds off the screen--not sure
if this gives you more points or not.
