Ace Combat 5: The Unsung War Cheats

On the mission Demons of Razgriz you have to fight the Hrimfaxi. While you fight it, it will dive back into the water and pop up someplace else. Well, if you climb to an altitude of 7,000 feet or more, and you look down with the right control stick, you can see where Hrimfaxi is hiding in the water. This will give you an advantage when you need to know where it will pop up next.

Hint: Easy Win Against Sinfaxie Or Hrymfaxie
Use the A-18C, F-2A, Raffle-M, or F-35C. When you go against the Sinfaxie play the level till the Ark Bird shoots it while it’s under water, then when it is on the surface use the plains special weapon which should be the LASM (Long Rang Air to Surface Missiles) and lock onto the Sinfaxie Not the Launcher or any of the SAMs or AA Guns.
When you go against the Hrymfaxie do not use the LASM until after you've damaged the Hrymfaxie and it surfaces to launch its ballistic missiles at allied ground troops.

Unlockable Aircrafts
X-02- the X-02 will appear after you've collected all available aircrafts(except the FALKEN)

The FALKEN will appear in the hangar once you've collected all objects hidden in special warehouses. These warehouses are in Missions 12A, 12B, 16A, 16B, and 27.

Just like in Ace Combat 4, this game also gives you the option of the "Free
Mission", when you have completed the game, go to the main screen and select
Free Mission. You can now play any mission in the game, using any plane you
have previously bought.

Even more difficulty settings...
When you have completed the game, there are a few more difficulty settings that
you can choose from. These are great if you completed the game with ease, and
want more of a challenge!

Music Player
After completing the game, just go back to the Title screen and go to options. The
Music Player option will now be available. With this, you can listen to all every
single track from within the game. This is probably the ONLY place you will be
able to do this, without having to actually play the game

Beat Arcade Mode on any route to add 13 more tunes for a total of 64 musical scores in the Music Player.

In mission 16A "Desert Arrow", the ground is mostly desert with lots of circular patches of green (farmland, I suppose). One patch is in the shape of a Pac-Man ghost. To find it, go to grid section 5D (upper left grid is 1A, with numbers going across and letters going down). It's in the northern middle section of the grid.

Shoot down the indicated target or complete the listed task to unlock the paint for the corresponding aircraft. Note: All planes must be bought before the paint becomes available.

When you get shot down in Ace Combat 5 you can still fire your guns and missles however you can't target enemies Therefore it is very hard to destroy enemies
