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 game will confirm that you have unlocked the extra characters, as well as other cheat codes.
Teenage Mutant Ninja Turtles
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 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.
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: 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.
