2D Mario from Super Mario Bros. 1
One time only in the game you can change into a 2D Mario walking around on a 3D landscape. It is prety cool. The image turns sideways when you tern diagonal. In booster tower, I think it's right after the room with a switch that opens a pasage of booster pass. There is a large curtain near the exit. Go in the right side and coming out the right side wont do it but going in the right and coming out the left causes the transformation.

Cameo: F-Zero and Star Fox
In the uppermost right corner, you can see F-Zero and Star Fox racers in Hinopio's shop on Barrel Volcano.
Cameo: Link and Samus
These two popular characters play no significant role in the game.
To find Link, return to the Rosa Inn (same place where you played with that Gaz girl) after you find the 2nd star. He'll be upstairs sleeping in the bed. Try to talk to him and the Zelda Mystery noise plays.
To find Samus, go to the Mushroom Kingdom after securing the 5th star. Go into the castle, then to the guest room. Samus will be sleeping in the bed. If you talk to her, she says she's resting for Mother brain.

Samus Cameo 2
When you reach Booster Tower and get to the top where you talk to *some-what spoiler character* through the door. After this conversation look in the box where Booster and his Snifits are talking. There is a samus action figure.

Easy Level Up's
Look for a place where a star is next to a save point. Save, then get the star, level up as many times as you can. Then die (in game) and you will still have your levels, aswell as be able to use the star again :-).

Geno 9999 attack trick
After you acquire Geno, put him in your party. After he learn the move Geno Whirl, enter battle. Use Geno Whirl and a tornado like wind will come onto the screen. Push Y right before it leaves the screen for 9999 attack points.
Note: You will hear a crackling sound if you did it right. This does not work on all enemies (ie bosses).

When you are on the path going towards Rosa town, get to the section where all of the ShyGuys are standing on top of the treasure boxes. Go to the bottom right side of the screen to the exit. Hit the box next to the door and get a few coins (but do not empty it, leave some in) then go through the exit. As soon as you go through the exit, go back through and hit the box more times (still don't empty it). Then just repeat this until you have a many coins as you want, it won't go empty!

Mushroom Castle's hidden box
Many who search for all of the Hidden Treasure Boxes are stumped by the one in the Mushroom Kingdom Castle.
Ordinarily, you can find any hidden Treasure box at multiple points in the game. The one in Mushroom castle, however, has only 1 oppurtunity, and that is at the beginning of the game. On your first visit to the castle, be sure to jump on Toad's head and ride him to where the door is. You can now jump onto the ledge right above the door and find a Treasure box that can't be found at any other point in the game.
