选关：在标题画面时按顺序输入1P的上上下下左右左右ABB，然后选择需要玩的人数后按开始进入游戏，选定忍者神龟后会出现选关及选择难度的画面。*上方的SCENE是选择关卡，DIFFICULTY是选择难度，PLAYERS是选择人数，共分三种：3人、5人、7人，SOUND是音乐测试。用方向键选择完毕后按EXIT退出。即会进入你所设定的情况。
模拟器:FC游戏很多都可以修改的，根本无须外界的任何工具，模拟器本身就可以作为修改器，经过本人的摸索终于找出了一些作弊方法，现与大家分享忍者神龟2、3的99条命修改方法，忍者神龟血不可以修改但是生命数可以修改方法如下，由于汉化版语言可能不一样，便说快捷键。如下：
1、忍者神龟2：即没有绝技的那种，选人的界面是“田”字行的那个**关底下是火。先打开ViruaNES，载入游戏，选好人，打开，进入**关，可以看到人数那里显示“REST 2”，然后点快捷键“Ctrl”＋“Home”，或者选“工具”菜单（第四个菜单项）**个选项，出现修改代码的一个框，你如果自己不会修改操作吧？照我的做就行！在*下边“数据写入”栏，左边的地址里填写004D，数据栏里写99，点击右边的“写入”按钮，这就完成了对玩家1的生命数修改，如果你是两个人玩，那就再在地址栏输入004E，同样数据栏里写99，再次点击右边的“写入”按钮，关掉这个代码修改框，可发现人数并未变成99，先别急，每人都死一条命试试？看到效果了吧？人数变成了98，这样把所有的关卡打完，人数绰绰有余。
2、忍者神龟3：即美版忍者神龟2，每人有一种绝技，选人界面是四个一横排，**关是沙滩的那种。按照上述方法写入新值即可。给地址006A写入99，这是修改玩家1的人数，地址006B写入99，这是修改玩家2的人数，回到游戏，死一条命，可以看到“R＝∞”，实际上是99条命。
怎么样？是不是很高兴？如果你还想知道更多的秘籍，可以联系我，邮箱jk_1986@126****。如果你没有得到结果那就看看你的版本，上述方法在VirtuaNES 0.92汉化版下正常，再就是看看你的操作是否正确，是否填写正确的地址，数据是不是99？不要贪心写的太大，99足够。*后别忘记点“写入”后再关闭修改返回到游戏。

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 ***ear, 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。
