Tetris Attack

Go to 'vs' in the menu selection, then go to the 'password' menu. Input one of these codes:

Go to the 1P menu, then 'stage clear' and then to the password section. Enter one of the following to go to the corresponding level:

Good Ending: Beat the game using no continues.

Bad Ending: Beat the game with at least one continue.

In the ending credits for the VS mode hold select and use the D-Pad to control Yoshi.

To enter extreme mode on 1 Player VS mode, highlight the hard setting and hold L and up and press start. The background should change to red.

If you have a controller with a "turbo" option for buttons A or B, you can use the following exploit against the CPU so that you always win!

First, when you turn on the game and Yoshi appears in front of a blue screen and says "Nintendo," press B, A, L, L. You should hear a confirmation code when you input the cheat correctly. This will remove the "freeze" that occurs when you or your opponent makes a combo or a chain. In other words, the blocks never stop rising. After entering the cheat, activate turbo for either A or B. Once you are competing against your CPU opponent in splitscreen, place your cursor over any two blocks or one block and an empty panel, and hold down turbo. The panels will switch back and forth so quickly that your blocks will not rise, nor will garbage blocks fall on you! Eventually, the speed of the rising blocks will surpass the CPU's ability to get rid of them and you will win!

Although it takes a while in later stages, you can use this exploit to beat every difficulty in VS Mode.

After the title screen select 1 player game, then the fourth selection, then the second and enter the following chain.

When playing 2 player VS mode, at the screen to choose a character, hold down both the R and L buttons on both controllers at the same time and you can select one of the evil characters to play.

Choose the 1p Vs. mode, and move the cursor to 'Hard.' Hold L and Up, then press A. The game just switched to Super-Hard Mode!

On the VS. mode for 1P game, as soon as the Rainbow screen goes away, QUICKLY hold X&Y. You will be able to select any of the rescued characters!

On startup, Yoshi says 'Nintendo!' Press B,A,L,L during this time and you'll hear a tone. The game just upped its dif- ficulty! Each time you perform a combo or chain, the stack will NOT stop rising! Good luck!
