New Super Mario Bros (DS)

1-UP Mushrooms
1-UP Mushrooms can be found by hitting/smashing blocks. They give Mario an extra life.

99 Lives
this is more a trick then a cheat, but in level 2-4, at the very end of a level, there is a turtle walking down the stairs leading to the flag. at about the 4th step, jump on him. here is where it gets hard. you need to jump on him so when he ricochets off the wall, you continue to jump on him. after that, don't ove so mario is just jumping n the turtle, and after a while, he will get 1-ups, and as long as you don't move, your lives will continue to go up till 99.

Accessing world 4 and 7
To access worlds 4 and 7 you first need to get a mini mushroom. You can get these at a toad house or in a game level. Then defeat the world 2 boss as mini mario. After the boss is defated you will notice a small opening at the bottom mini mario will fall in there and you will go to world 4. For world 7 defeat the world 5 boss as mini mario and mario will the go into the small opening at the bottom. You will then be at world 7.

Backwards slide
In World 3-A, go to the second "room", then go in the first pipe. You must be either Mega or Mini Mario to get the coin. To backwards slide, dash down one of the slopes, then turn back, still holding Dash. It will appear as if you are turning, but you will slide backwards. Make sure you hit the water before turning.

Blue Koopa Shells
You can win Blue Koopa Shells in Red Toad Houses. They give Mario a shell on his back, where he can dodge enemy attacks.

Chalange mode
Go to any world then press start and L,R,L,R,X,X,Y,Y a screen should come up saying "welcome to the secret Challenge mode.Think you can reach the goal? If you get stuck press start and choose return to map" you can not turn back.

Classic Goal Theme
Remember the goal theme from the classic Super Mario Bros. that plays when you complete a world? Well, it plays on this game, too. To have it play, you have to complete the world when the last 2 digits of the time are the same, for example, "199".

Coins
Coins can be found in the open or hiden within blocks. You also recieve 1 coin for each enemy you kill with fire balls. When you get 100 coins, you get an extra life.

Dancing enemies
Notice that some enemies in all stages will do some sort of dance or jump when the chorus in the background music sings. This does not include flying enemies, Bullet and Banzai Bills, and Bosses.

Deafeating Mummmipokey
Mummipokey is the final boss in World 2. He will hide underground and sprout back up. Before he comes back up you will see dirt being kicked up, so that is your warning. You will have a split second to move from that area. As soon as you comes up, jump on his head. Do that a couple of times and he should be dead.

Dorrie Fire Launcher
Whenever you're riding on Dorrie as Fire Mario, shoot fireballs at the back of Dorrie's neck. The fireballs will ricochet off Dorrie's neck and will fly into the air, easily killing any enemies.

Easily defeat Baby Bowser and Boswer in World 8
Before entering the castle, enter an orange mushroom house and keep the Mega Mushroom you receive. Enter the castle and do not use the mushroom until the boss Battle. As soon as you can move again, tap the mushroom and grab it. As Mega Mario, simply run into Baby and King Bowser and both will be defeated.

Easy lives
In World 1-1, hit the "?" block containing the Mega Mushroom, then run as fast as possible to the end of the level and smash everything in sight. If you crash all the way through to the flagpole, you can earn up to five 1-Up Mushrooms. Enter the world again and repeat this as much as desired.

In World 6-6, when you find five pipes at the end of the level, go in the third pipe. You will get shot out to the top of the flagpole.

Fire Flowers
Fire Flowers are usually found after you find a Super Mushroom and give you the ability to fire, fire balls at enemys. If you get hit once you go back to the "Super Mushroom" form and if you get hit twice you go back to your original form.

Good way to get lives
Go to w1-lvl1 and keep doing that to get lots of lives.

Hidden star in World 1-2
Go to where the Venus Flytraps are. There will be two blocks. Go to the first block and jump. You should see a star.

Infinite lives
In World 2-4, just past the two Piranha Plants (after the mid-level point) you will come to a staircase with a turtle coming down it. Jump on the turtle just as it is about to go off the third stair (third from the bottom). If done correctly, Mario will continue to jump on the turtle and earn up to 99 lives. If you miss the turtle, go back towards the left and return to the staircase and the turtle will respawn. This is a reference to the original Super Mario Bros., in which you could do the same trick to get unlimited lives.

Go to World 7-4 as Mini Mario. Go through the stage while staying on the left side. You will eventually see a "?" box and a ledge. Jump on the box then to the ledge. Jump off the ledge, making sure to stay against the wall and you will reach a platform with a pipe leading to a red flagpole. You will unlock a 1-Up mushroom house to the north of World 7-4, which never disappears. You can continue to get 1-Ups until you reach your maximum of 99.

In World 7-5, throw a Koopa shell in-between the two Bullet Bill cannons to get an extra life every four seconds.

Infinite Toad House items
Successfully complete all stages, including the lettered bonus stages, then load the saved game file and Toad Houses will no longer disappear after you take the items. The only exception are the ones that appear based on your timer when you finish a stage.

Mega Mushroom
Mega Mushrooms are the rarest of all mushrooms and causes Mario to grow to a huge size. Then Mario can crush obsticales, enemys and blocks. You can earn 1-UP mushrooms, depending on how much damage you do.

Mini Mushrooms
You can find green mini mushrooms in blocks just like Super Mushrooms. They shrink Mario, giving him the ability to walk on water, hop on enemys (but you can't hurt them), fit into tight places (including small tubes), and glide horizontilly after jumps.

Play as Luigi
When you beat the game, at the end of the credits, you'll see Bowser Jr. lugging his dad off to somewhere. Plus, if you were observant, you'd notice a code. When you are about to select a file. Highlight yours, then hold L and R, and press A. If you did it right, Luigi's voice should say his name, and you should be playing as him rather than normally playing as Mario.

Save anywhere
Suuccessfully complete the game to get the option to save your game anywhere. When you start a new game, the "Save" option will be available under your menu in the map screen.

Saving
You can only save after you beat a tower or castle for the first time or when you open an area by using 5 Star Coins.

Secret Challenge mode
Successfully complete the game. Start the cleared game file, then pause the game while at the world map and press L, R, L, R, X(2), Y(2). If you entered the code correctly, the message "Welcome to the Secret Challenge mode" will appear. Similar to the original Super Mario Bros. for the NES, Secret Challenge mode will not let you backtrack in certain levels. To indicate whether a level has a Secret Challenge version, the new right arrow icon will be lit in the top right corner of the map screen.

Secret exit in World 7-4
To locate the secret exit in World 7-4, you will need a mini-Mushroom (in storage, if possible). Make your way past the mid-level point and upwards to the left side of the screen (high up). You will eventually come to a flying "?" block. Use the mini-Mushroom to make Mario smaller and jump onto the block to stop it. Then, use the block to jump into the little opening in the brick wall. Make a "C" jump (backwards C) and jump up and to the left to land at the top of the wall. Go over and you will see a small pipe that only mini-Mario can fit in. Take this pipe to reach the red flag secret exit.

Secret exit in World 7-5
Just before you reach the giant Bullet Bill, you will see a pipe that is covered in blocks. Use the Bob-ombs to blow up the blocks and then access the pipe to reach the red flag secret exit.

Secret exit in World 7-6
After you reach the mid-level point, you will come to an area with two rows of bricks. You must be big, but not mega-sized to perform this trick. Knock out the middle brick on the top row, then knock out the third brick in the bottom row. This will cause a vine to grow. Climb the vine and make your way to the end of the level above to reach the red flag secret exit.

Inside are four background patterns you can choose for the touch screen. You can purchase these with Star Coins. The fifth and final pattern can be purchased for 20 Star Coins when you have collected all Star Coins, completed all stages, and found all hidden exits.

Super Mario Bros. reference
At the end of any stage except Bosses, touch the flag when the last two digits of the clock are the same (for example, 311, 222, 099, 111). When the flag is lowered, the old chime (for clearing a level) from Super Mario Bros. will play as you walk into the castle. Once inside, and the flag is raised, fireworks will go off corresponding with the number repeated on the clock. For example, if the time is 099, then nine explosions will be set off; however, if it is 211, only one will go off. The time will also set off other events, as stated in other cheats listed.

Super Mushroom
Super Mushrooms are red and can be found by hitting blocks. They double your size and allow you to be hit once without dying. If you get hit you revert back to your smaller, original form.

Toad Houses
There are three different Toad Houses you can go to: Red, Green, and Orange. In Red Toad Houses you can get a Super Mushroom, Mini Mushroom, Blue Koopa Shell, or a Fire Flower. In Green Toad Houses you can get 1-UP Mushrooms. In Orange Toad Houses you get a Mega Mushroom.

Toad Houses
Usually, after you complete a level with the classic goal theme playing, a Toad House will appearin the arrow space. The 1-Up houses, Mega-Mini Mushroom houses and Item houses have a chance of appearing.

Towers
There is atleast one Tower in each level. In Towers you start at the bottom and work your way up, instead of the usual horizontal design. At the end of each tower you face Bowser Jr.

Warp from World 1 to World 5
Go to the tower in World 1 with the Blue Shell power-up. Go to the first pipe that shoots you up into the air. On your way back down, go in the gold door. There will be a lot of randomly moving platforms. On the right, there is a gap that always stays the same size. Go through it and you will see three blocks. Use the Blue Shell ability to break them all, then break the last three. Go to the right and finish the level to reveal the World 1 Warp Cannon, which will shoot you to World 5.

Warp from World 2 to World 5
In Secret Stage 2-A, there is a secret exit to the stage that will grant you access to the Warp Cannon in World 2. Near the end of the stage, there is one last spin jump platform you need to use to reach the final Star Coin. Instead of stopping once you get the last Star Coin, continue falling to the right and press Jump at the same time you land on the red turtle on the final platform to get enough jump height to reach the platform with the pipe above you in the little alcove. Go through the pipe and exit the stage using the red flag.

Warp from World 3 to World 6
Enter in the Ghost House as Mini Mario. Go to where you see a huge ghost next to a pipe in which you have to press a switch to turn them into red blocks. Go all the way to the right and do not get hit. Keep wall jumping until you get on a secret ledge with a door. Go in the door and jump on the red flag, then use the Warp Cannon to get to World 6.

Warp from World 5 to World 8
Enter the World 5 Ghost House and get a Mushroom from the blocks. Then, go up the stairs untill you get to a place with three brick blocks on the left side of the screen. Stand on top of them and jump to reveal three invisible blocks. Next, wall jump on the left side to get on top of them. Stand on the middle raised block and duck, then jump to reveal a block with a vine in it. Climb up the vine and a Boxing Ghost will appear. Jump off the vine to avoid taking damage from it. Kill it and climb back up, and enter the door. Kill the two Walking Pumpkins and stand in the middle. The platform will wobble and as long as you stay in the center you should be fine.
