There are not many games which have made such a great comeback from being quite obscure to being in the top ten like Doraemon. Quite surprisingly this game was first released as part of the Nintendo game system in 1986. The simple layout and easy to moves can easily be seen as the first reason of popularity of these games today.
When most of the games are aiming at complicating things and adding thousands of new graphics, this awesome game is classic as the original design has become quite a icon in itself. Based upon the Japanese TV show, the basic idea is always to complete different levels as fast as you can.
The different levels of games have some villains and bosses stopping your path. The idea to survive in here is quite simple you can either jump or move in slower pace to avoid being captured. The initial game did not have some cheats, but later versions have many such places where you can jump from different spots quite easily.
The level one cheats include the use of time machine. By using this cheat code you can bypass the introduction animation in here. Using this cheat is quite easy you only need to press button of A and B.
Similarly if you wish to jump from level one to second, the same A and B buttons pressed simultaneously can give you this jump in here as well. You can easily skip the lengthy intro in here as well as the game starts instantly.
The level third can be started by using this system as well. All you need to do is press buttons A, B and Select at the same time twice. The second time you should press start, the game will start at the third level. Similarly you can easily restart the game after being over by pressing the up direction button when the game over comes. When start appears you should select that the game will start from the level you left before.
