Unlocking all extra characters:
Use the following trick to unlock all extra characters
at once. Make sure you have a saved game file for the game. Set
the system date two or more months ahead from the date that you
saved the current game. Insert the game disc and start it. At
the title screen, go to "Continue Game". When you get
to the level selection screen, go to "Home". You will
see every playable character unlocked. To confirm to the game
that you have unlocked the extra characters, just exit home, start
any stage, and complete it. When you have finished, the game will
confirm that you have unlocked the extra characters, as well as
other cheat codes. Alternately, successfully complete the Teenage Mutant Ninja
Turtles arcade game.

Teenage Mutant Ninja Turtles
arcade game:
Got to level 9-1 and get the hidden Antique. Do this
by going down one of the alleyways. There will be a pile of crates
and a broken down bus. Jump on the crate and onto the bus. From
the bus, jump onto the building . There should be two crates here,
containing Pizza and the Antique. Then, complete the level and
defeat all the Purple Dragons, Foot, and Mobsters. Next, go to
the " 2nd Time Around". If you look through the different
objects in the "NY" section, you will see the image
of an arcade. Select the arcade to see information on it. When
you exit out of the information, the message "Classic Arcade
Mode Unlocked" will appear, and that option is now on the
main menu at the title screen. Note: Do not worry if the screen
remains black, or the arcade main screen takes a long time to
load; this is normal. In the arcade game, press Circle to get more lives instead
of quarters. The joystick and certain buttons including the pause
feature do not work. The character selection is just like the
arcade. Each controller controls a different turtle. You cannot
which turtle to assign to a controller. Controller one is Leonardo,
controller two is Michaelangelo, controller three is Donatello,
and Controller four is Raphael.


Hint: Defeating Spasmasaur:
Hitting the tentacles does not do anything. Instead,
if playing in single player mode, use Donatello and single (or
double) jump directly up to the Spasmasaur's head and hit it.
The Spasmasaur will turn red. Run and lure it into the closest
wall. Repeat this until it is defeated. If playing in multi-player
mode, have Donatello approach Spasmasaur and have everyone else
stay as far away as possible. Then, and jump attack the Spamasaur's
head, lure it into the wall, and repeat.


Hint: Backyard: Completing as Leo:
In the level 0-1 "Backyard," you do not need
to change to Don, Mikey or Raph. All things can be completed with
Leo. After slashing through the metal fences, walk up to the crate
Raphael is supposed to move. Repeatedly use weak attack to move
this with Leo. Note: This might take a bit of time. There are
two ways to cross the river using Leonardo instead of Michelangelo.
You can either climb the boxes at the far wall and cross over
the top path, or use Leo's aerial attack to cross. When getting
to Donatello's challenge (technology), just use weak attack on
it until the lasers are disabled.


Hint: Feudal Japan: Secret levels 6-4 and
6-5:
To reach the two levels on top of Feudal Japan, in
level 6-3 go near the bridge. Use Leonardo to cut down some trees
toward a clearing. You will go toward a beach (with an antique).
Then, use Raphael to move a large rock leading to a cave.



Glitch: Character's feet pass through wall:

Whenever you do a wall-jump, look very carefully to
see that your character's toes (or sometimes even their feet)
are passing through the wall.
