One way of storing a Mega Mushroom in your inventory like the other items you collect is to grab the Mega Mushroom and hit a '?' Block at the same time. Doing this will store the Mega Mushroom even if you technically had enough room to 'grow'. This is easiest to do in World 1-1.
An easy way of nearly always getting Mega Mushrooms in 2-Player mode is to let the other player get more stars than you (usually more than 5).
To get a big orange mushroom to appear over your head in Versus mode you need to first get a mushroom on the touch screen and then collect 8 more coins. Note: This can only be done once per match and only works on certain levels.
Save the game and enter a red mushroom house, then pause the game when Toadsworth makes the roulette block appear and you see the Fire Flower. If you then quickly press 'A' twice you will get a Mini Mushroom icon on the touch screen which you can tap any time you want to become Mini Mario.
If you Ground Pound on top of a multi-coin block when you are in a big form a mushroom will appear after ALL the coins have dropped out.
After you beat bowser you can spend 90 stars to get the star world
On level 8-2 it is a red flag after the huge. Goopas ,in the orange tube.and there you are. Oh and when toad is in trouble you go and save him .because if you go the whole level without killing toad.toad will give you 3 lives and try to hit the top of the flag.
After you reach the mid-level point you will meet an area with two rows of bricks. To do this trick you must be big but not mega mushroom sized. Heres what you have to do, knock out the middle brick on the top row then go on to knock out the third brick on the bottom row. This will make a vine grow, climb the vine then start making your way to the end of the level and reach the red flag. Hope this is helpful to all you's out there if you have any further questions or opinions - thoughts feel free to comment below and i'll try to get back to you ASAP (for anyone who does not know what ASAP means it means as soon as possible). Thank you for taking your time to read this.
In this game when you've just completed a level I know how annoying it is when you can not save. Only when you have completed the whole entire game can you save after you have finished a level. Unless... Whenever you finish a level and want to save go into one of the mushroom houses and unlock one of the mushroom houses(you will of course need 5 star coins). This trick is very helpful as some of the levels are very irritating and when you finally complete it it does not save in till you get to a certain point but you can't get as far as that because your mums moaning at you to come and eat your tea!! LOL :( Hope this is helpful!

Remember it's no use unless you have 5 coins which is pretty simple so try it out!
I think we all agree that World 1-1 is the easiest level in the whole game so for extra power ups and helpers just go back to the very first level and play it to get mushrooms etc.
When you get to the end of your game finish and land the timer on the same two digits at the end eg. 011,288 etc. When you land the last two digits on 11,22 or 33 it will reward you with the red mushroom house which you then go in and get a random item box. When you finish and get the timer on 44,55 or 66 it then gives you the green mushroom house which you go inside and get 1-ups. Stop the timer at 77,88 or 99 and you'll get a orange mushroom house which will award you with a mega mushroom. Hope this is helpful!
This is probably the easiest and fastest way to get infinite 1-Ups. First, just go through World 2-4 as you normally would, and stop when you get to the staircase at the very end of the level. Stand on the first (bottom) step of the stairs, and wait for the Koopa to come. As soon as the Koopa lands on the second step, jump. If this is timed right, you will keep bouncing on the shell and start getting 1-Ups. If you mess up, just walk to the left a good distance and when you come back to the staircase the Koopa will be back.
In the menu go to select world menu and hold L and R and then press A on your world
When at the main menu, select Mario Game. When you get to the file select screen, have the file you want highlighted in light green. Press L,R, and A at the same time and Luigi will appear where you last left Mario.
If you want challenge mode, go to the first island's map and press start than push LRLRXXYY and than a message will pop up.
First you need to click on Mario game in the begging then press and hold L and R at the same time click on the file you want. Then it will say Luigi but you have to have your volume up to hear.
Hey everyone, I know this game is kind of old but some people don't know how to play as Luigi on this game, so I've decided to tell you. When the screen starts up and you go to the selection to click on a saved game file, press and hold both of the L + R buttons on the top of your DS at the same time as you're selecting the saved file, and you'll hear Luigi talking in the background. You will now be able to play as Luigi. But if you get a game over or restart your DS, you'll have to redo it again or you'll be playing as Mario. BTW, if you're using DeSmuME, an emulator for the Mac & PC to play Nintendo DS games, hold the Q + W keys on your keyboard. Hope this helps! Enjoy playing as Luigi!
When you start the first level of the game, play the level until you have passed the mega mushroom box and the three bricks that follow after that, then you will see two other bricks that you see exactly after the three that had followed the mystery box containing the mega mushroom. Now jump on the two bricks then walk on to the right brick of the two, then jump once more. When you have jumped you should notice the hidden box that contained the vine. When you have climbed the vine, to your right you will see a box, when you have hit that box a 1-up will come out. Then if you continue to your right there will be a platform with coins over it. That is the second hidden vine in 1-1.
In world 1 bowser junior castle when you go up the pipe that shoots you up you go back down go into the door there will be another door there do not go inside in the diagnol right corner two blocks will turn into stairs walk into the part at the top of the stairs then you will need a turtle shell to bash the bricks down behind the bricks is a pipe go into the pipe then you should be at the red flag if not start again
Instead of immediately jumping onto the flag pole at the end of a stage, take your time and watch the clock. If you hit the flag when the last two digits of your timer are the same (example: 133, 211, or 099) you'll unlock a mushroom house on your World Map. If the last two digits are 1, 2, or 3, you'll unlock a red mushroom house. If the last two digits are 4, 5, or 6, you'll unlock a green mushroom house. If the last two digits are 7, 8, or 9, you'll unlock an orange mushroom house.
So,when you're at the main menu,you click the Start Game thing and it will take you to the screen where you select a file.While holding down shoulder buttons L and R select the file you want to play as Luigi in with the A button.
And voila!!!
You can play as Luigi!!!
P.S.
After you have finished playing,you don't need to save the game.You just switch the console off then next time you play just use the cheat again.
Good luck!!!!
To get luigi you can just press the l and r a buttons and the a button too and you will hear luigi then you can play as luigi next time you play bye:D
First, go onto World 1-1 and play the beginning normally.
When you get to the part with the mega mushroom, don't just grab it. Wait until it is on the very edge of the cliff to grab it. If your timing is right and you keep moving forward, your "big-ness" should last until the end of the level, letting you destroy the staircase and even the flag, which give you 5 extra lives. Enjoy!
Its simple just get a mini micro mushroom then go to world 2 fight the boss on the last castle to unlock world 4 ten do the same thing on the last castle on world 5 to unlock world 7
First of all you need to play the first level of the game then find the mega mushroom then wait till it's at the right edge then get it don't jump keep running and destroy as many things you can and do you will get at least five lives and keep doing that untill you get 99 lives

Mummipokey is a tricky boss, harder than the ones you have faced before him. Wait until he is shorter, for example 2-3 heads, then Ground Pound him. You must Ground Pound him three times to win. If you beat him as Mini Mario, you unlock World 4.
In this fight, you face Bowser, but it is actually really easy. Just wait for him to you, then jump over his head then hit the switch at the other end to send Bowser to his doom.
For this battle, just stomp on Bowser Jr's head three times to win. It is recommended that you go in to the battle with a Fire Flower or a Mega Mushroom. Watch out when he hides in his shell.
In the Mario VS Luigi game, If you in the Fire Flower form and your rival is shrunk tiny (with the Tiny Mushroom), you can kill him with a fireball! That's right: a direct fireball hit of your rival while tiny kills him, which takes out a life (if in VS Rules Lives are set to 3 or 5) and a Big Star!
To get the cannon you have to make it to the yellow door. Go through the gap in the top right corner.
If you have a Mega Mushroom go on a Cannon Level
And use the Mega Mushroom and keep ground pounding and you will see Coins And Goombas falling from the sky. OMG!!!!!
To be outstanding at Picture Poker, concentrate on the Stars and Marios. If you only have one pair in your first hand get rid of all the others and go for that one. Remember, higher ranked cards mean you will have a better chance of winning.
To be successful at Lakitu Launch, just keep shooting and aim at the goal.
Snowball Slalom: Roll a snowball down a hill to achieve the fastest time.
Lakitu Launch: Shoot as many Spinies as you can in the time limit.
Danger, Bob-omb! Danger! Dodge lava as a Bob-omb to achieve a big score.
Whack-a-Monty: Whack as many Monty Moles as you can in the time limit, but be wary of Luigi.
Balloon Racing: Try to reach the goal with a Yoshi riding balloons.
If you want to make the flying red ? Boxes move quickly and do it by hardly doing anything, this cheat will help. Just enter a level you have completed already, then pause the game, and finally, choose return to map.
There are all sorts of invisible stuff, like a coin a flower or even a vine. Sometimes the vine takes you to a red flag to unlock something new! Sometimes it gets coins and even a green mushroom
If you looked at the ending of the credits of the game where is said "THE END" in the background it says L+are+A=??? And if you do that on the main menu, you will play as luigi!
In world 2-castle (Make sure challenge mode is on) When you get the bills you see an space all away at a the top move unit you see an little opening go back up and jump on the bill when you get to the opening wall jump and you will be at the top. Careful! When you are blocked by a wall jump. I hoped it worked.

Go to world 1-1 and get to the check point. After you make it there let yourself die. Once you go back to it there will be three blocks sepperated and you go to the middle one, get on top of it. Once your there jump and you hit a hidden cube that has a star in it.
Thanks for reading
In the start button press the buttons LRLRXXYY you make a old mario bros, and is more hard
Okay to do the runing flip you run while you are running press b wait1 sec then press b wait 1 sec press b and you will flip
Note:do not stop or run into anything while doing it or it will not work
Alright, everyone wants big right?to get him on multiplayer(yes, I only know how to get him on multiplayer.)let your self die(on purpose) until(if playing to 5 stars)the opponent has three stars.get eight coins and watch the magic happen!(don't let your opponent get it before you!)P.S., the BEST place to get him on is the grass place with the goombas and the turtle!
When he slides toward you try jumping over him, and he'll probably fall off the board thing-ie. Will probably work better on the, um, ones that tilt.
To get to world, you have to beat the mummie pokey boss, in the modern blue boss castle, with tiny tim (mini mario). To make that easy , just jump on him in normal form 2 times. NOTE: do not ground pound him., and than drop the mini mushroom onto your scean and than ground pound him. Than off to world 4 you go. Now to get to world 7, there is 2 ways of doing it,. The easyest way is to go in the gost house, and hit the ! Swicth, or what ever switch is there. Than jump on the tube part,note:requirs mini mush, and wall jump to a platform of some kind and go through the secret exit. The other way is the same as the world 2 cheat, but different boss
This is just a few hints mixed together for people who are stuck on specific parts.
--World 4--
Defeat the W2 Boss as Tiny Mario.
--World 7--
Defeat the W5 Boss as Tiny Mario.
--Luigi Joins The Action--
While you are picking, on the main menu, Mario Game, hold are and L at the same time.
--World 2 Cannon--
Go to W2-3. While in the room with the water, go up the tube at the top while in the water. Before the water level drops, press the button hanging down. It will rise further. Go through the tube at the top and straight out. You will find a red flag. Now go to the bonus level, W2-A, and while at the end, don't go through the pipe at the bottom, instead try for the top pipe while spinning and hitting ..
To do this you must first load a saved game file which you have cleared every level (including the lettered bonus levels). Toad Houses now 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 level. If you want to have ALL of your Toad Houses back, save the game and then intentionally lose ALL of your lives. When you return, ALL of the Toad Houses will be restored.
When you have a turtle shell look for an arrangement of blocks that look like stairs. Set the turtle shell down on the stairs and when the turtle inside comes out jump on his head. If you time it correctly Mario or Luigi will keep jumping on the turtle's head and you will build up lives. When you have the desired amount of lives jump off.
To earn Mario an extra life you can either collect 100 Gold coins or at the end of a stage jump up and land on top of the flagpole.
To play as luigi instead of mario press the left and right buttons on the back of the nintendo when you pick your game file.
To play as Luigi, select your file while pressing L+R
At the end of a level, get on the flag with a time of {the last 2 numbers count} 11,22,33,44,55,66,77,88, or 99.There will be a certain Mushroom House that will pop up at the begining of the World you are on & there will be Music and lots of Fireworks!}How many fireworks show up is depending on your time.Example:11-1 firework. 22-2 fireworks. 33-3 fireworks.44-4 fireworks.55-5 fireworks.66-6 fireworks.77-7 fireworks.88-8 fireworks.99-9 fireworks.}
Happy Playing!
:D -Moemoerocks
After you beat the game,you can use the Star Coins to buy stuff.But why would you waste them buying things when you can save them?!To Save, just pause the game and there should be a new option that says SAVE.
{I'm not entirely sure, but I think this is only avalible when you actually BEAT the game.}
If you do a ground pound {Jump then press Down on the D-Pad} but before you hit the ground, press Up on the D-Pad and you will land on your feet instead of doing a ground pound!
Its very simple yet very complex.
To get to World 4 you have to beat Level 2-Castle with a Mini-Mario/Mini-Luigi.
To get to World 7 you have to beat Level 5-Castle with a Mini-Mario/Mini-Luigi.
Also, after you beat the game push the following buttons in this order:L,are,L,are,X,X,Y,Y.This takes you into Secret Challenge Mode where you can't go backwards. {Like in Super Mario Bros,the orignal you can't go back for anything.}
Thanks!Please Rate Thumbs Up If I Helped!

SSBADFGASD
BASDMASDBS Now if you try to solve this it might be wrong because I am just using it as a example. It's better to use D first. Itt might not work for you but for me it worked and I only lost 3/22 D.
After you beat the game,while viewing the credits you can tap them and you will hear different sounds from the game
Just go to the ghost house in world 5 then when you see the steps and the 3 blue blocks run and jump on the blocks. Jump then jump on the blocks you just made appear then on the middle block -jump- and a vine will grow to a door. Go into the door. You'll find the victory.
Get the big mushroom in order to jump over Big Bowser and Bowser Jr. Then after that just hit the red button then Bowser will fall into the pit or just crunch Bowser Jr. And jump on powerful Bowser. P.S. Jump over all of Bowser's attacks.
Bowser is made out of bones. Not sure, but try to use fire power or just step on the red button that has a skeleton on it to defeat him.
Go to world 2 the third level and end the level a different way. The way to end the level a different way is to get to the part where you have to push the question mark button then when the water rises go to the hole which is up then hit the button to make the water go even higher but do it before the water starts to go down. After you hit the button swim up and you will end the level a different way but you have to see the red flag. P.S. The red flad means you will warp.
Go to the ghost house. If you want to go to world 8 just beat it a different way. As soon as you see a door, don't go in it go to the second door you see. Then the game will go on a different way. Then when you beat the level you will unlock the cannon that takes you to world 8. But the thing you have to do to unlock world 8 is to either stay on the platform that takes you up or when you see another way to get out of the ghost house.
When you are at the first boss on World 8 all you have to do is hit the red skeleton button.
World 1 Boss - When Bowser is near you, jump on the platform then jump over Bowser then hit the red button the one with the skeleton head on it.
World 2 Boss - When the mummy is big, jump on the wall and if you have tiny power you can jump on the wall and glide off it and then when you are right on top of the mummy jump down and bash him.
