Go to Booster's Tower and step behind the curtained area. You will be transformed into 8-Bit Mario from the NES version.
9999 HP hit with Geno
Put Geno in your party then in a battle use Geno Whirl. When the ring goes just out of the screen press "Y". You'll hear an explosion sound and Geno will have done 9,999 points of damage!
Note: This doesn't work on bosses or boss like creatures (i.e.
Jinx or Box Boy.)
Best Weapons and Items
Here's how to find the best weapons and items in the game:
The frying pan for the princess:
To receive this weapon, beat Nimbus Land and go to Moleville. Walk into the store and go to your left were a funny looking mushroom man should be selling things. In his inventory there should be a frying pan which he is selling. I strongly advise you to buy it.
The lazy shell for Mario:
Retreive the seed and fertilizer and bring it to the gardener house which is somewhat hidden on a new road. Climb the beanstalk and retrieve the goodies.
Fertilizer and Seeds:
The fertilizer is in nimbus land after you beat it on the far right were the guy was standing walk up it until you find a invisible path way were it is. I think I remembr that the seed is in Bean valley on one of the waterers.
Juice club cards:
These are given to you by the composer if you complete the melody. (The first one is found in the big frog's chart on the lily pad.)
Go to the second set of Booster pictures in Booster Tower (the ones by the locked door.) Place them in order and you'll receive a key. Use it to unlock the door and receive a chomp for Bowser. The real order is identical to the first set of pictures you saw when you entered the castle.
For a better ending, buy as many fireworks as you can in Moleville, then beat the game. The more fireworks you bought, the better the ending.
To fight Culex of the japanese version of Final Fantasy, buy the fireworks for 500 coins at Moleville, then trade it for a "Shiny Stone" at Moleville. Next, go to Monstro Town and go to the "3" door and open it with the Shiny Stone.
Grate Guy's Casino
First go to Bean Valley. When you get to an area with five warp pipes and a shy away, try all the pipes until you find a Golden Chomp. Defeat it and jump up 3 times. A secret plaform will appear. Jump on it and then right. To exit to the map screen where the casino will be go to your left. You need the "bright card" from knife guy at Booster's Tower.
There are several hidden items. Here's how to find a few of them. In these descriptions, the term "Search" means to jump around to reveal hidden boxes above your head.
Location: Starting Point
Directions: When you walk one screen from the start you will see a wiggler. Stomp on its head ten times without falling off (but don't enter the battle screen).
Prize: Frog Coin

Prize: Frog Coin
Hidden Red Essence
Go to the forest maze. When you get to the first save block, go beyond it a little and jump around the right side of the walkway. Keep jumping until you find the hidden treasure box with a red essence inside.
While riding "Moleville Mountain", push either L or R . Mario will honk the cart's horn.
How to Beat Jonathan Jones
To avoid fighting John the shark one-one-one or two-on-one, leave at least one blue bandana guy alive and destroy the rest. This will prevent the one-on-one without letting Mario die. If this guy irritates you, use Toadstool's Sleepy Time on him and keep him under until you're finished with Jonathan Jones.
How to Beat Smithy
First, after beating the first three bosses before Smithy, go back through the level. If you didn't have the shiny stone, then make sure you have 500 coins, buy the fireworks in Moleville and give them to the girl with the pretend market.
Afterwards, go to Tadpole Pond and buy megalixers from the froggie bar with your Saprano Card or Tenor Card, if you don't have it, go to Toadofsky in the second or third turn.
Then, go to Monstro town and to the door with Culex in it. Defeat him with Mario, Geno, and Princess Toadstool. Use Toadstool's Group Hug, Geno's Blast and Mario's Ultra Hammer or his Ultra Jump.
After beating him, you will recieve a Quartz Charm and equip it on Mario for better defense at the boss. Go back to Smithy and make sure you have Mario, Geno, and Princess Toadstool and use the same stuff you used for Culex but, if everyone is almost dead and the next blow will be Smithy's, use a megalixer.
At the first part of Smithy, use Geno's Blast on both Smithy
and the monster generator. Concentrate your firepower on the generator
(not Smithy) with Mario's Ultra Hammer and use Princess Toadstool's
Group Hug to heal the party. On the second half, just use regular
attacks on Smithy.
First go to Rose way. Then go to a room with Treasure Boxes then get the items and go out then come back then the Boxes are restored. The second is at Bowser's Castle. First beat Magikoopa and he will give you a Gold Treasure Box that will never run out.
Infinite Frog Coins
Go to lands end. Find the spot where the armored ant pops out of the sand. When he pops out jump on his head three times. After the third time you will get a frog coin. This can be repeated forever.
Spend a night at the Rose Town Inn and you will find Link from Legend of Zelda for NES sleeping in one of the beds.
If you have the Dream Pillow, sleep at the inn at Nimbus Land. Toad will appear in your dream and admits he is a monster. When you wake up, Toad is waiting for Mario to wake up, and he runs into a corner. Toad will give you three Red Essences!
After you beat Belome 2 and before you get to Nimbus Land, you can find Samus Iran of the Metroid Saga. Go to the Mushroom Village from the begining and go inside the castle. Go to the right from the hall into the next little room. Go up to the guest room and look at who is sleeping in the bed!!!!
The password needed in the ship is PEARLS.
Three Musty Fears' Flags
There are three monsters you find in Monstro Town when you sleep in a bed. They each will hide their own flag somewhere in the world. Here are their locations:
One flag is hidden behind the rose in Rosetown when you first
enter. Another flag is hidden underneath Mario's green bed in
Mario's Pad. And another is hidden behind the sign in Yo'ster
To get the Troopa Pin, go to the big cliff at "Lands End". There you will find "Sgt. Flutter". After talking to him, climb the cliff by jumping on the troopa shells as quickly as possible. Do it in under (12:00:00) to get the troopa pin.
Yaridovich Mirage Attack Tip
When fighting Yaridovich in "Seaside", he will do a mirage attack (create a duplicate of himself.) Here's a trick to find the real one.
Put Mallow in your party. When Yaridovich does the "mirage attack", use Mallow's "thunderbolt" power on him. The double that takes the least damage from the attack is the real Yaridovich.
To get the "Yoshi Aid" you first have to reach Smity's Factory. Once you've done this, do the following:
Go to "Yoster's Isle".
Go to the red yoshi and get some "Yoshi Cookies"
Go to the blue yoshi "boshi" and race him until you get a total of 15 yoshi cookies.
Next go to the baby yoshi, who is now fat, feed him all the cookies to get a Yoshi Aid.
