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.(Arc模式：9-1关，在一个小巷里有个破的公交车，通过他上到房顶，打开两个箱子，吃到宝箱，通关后，回到家里，看"2nd Time"模式，里面有张卡片，上面画着一个街机，看介绍后推出，屏幕上会出现“Classic Arcade Mode Unlocked"，然后退到主画面，出现街机模式.)
*****后面由于没弄出街机模式，所以没有测试***
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.
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.
ARC模式我没有弄出来，可能还需要什么条件，这里面所说的方法我试过了，没有成功。
