+50 life
When you unlock Vanilla secret 2 beat it and hit the half way point, BUT dont finish the level instead pause go back re-enter and collect the grey P-swich and go to the pipes with the jumping plants. hit the P-swich and then go and the grey coins to the LEFT <-. then you hear "whoo hoo! Bravo Mario" (i think) its says after 2 flowers come on the screen between them it says ??up! the "??" mean how many 1ups you should get around 25 grey coins and 51ups if done correctly.
(Note:There is a video of this on www.youtube.com)
Change in Seasons
Ok, this cheat is fairly hard and time consuming. Once you fight your way up into Star World in the sky, you will have to beat all of the levels up there. Soon the mountain in the middle will be acessible, and you can bring mario there. Enter this new realm and you will see a series of new, expert levels. Complete all of these levels to change the season. It will go from the basic Mario, to an orange and brown fall, with new characters, such as the Koopas will turn into Pumpkin Headed freaks. Have fun, and don't forget to save!
How to beat the game in 12 levels
Follow this guide to get to Bowser's door the quickest way possible.
Yoshi's Island 2:
Complete the level as usual. (Note: you may want to finish Yellow Switch Palace before moving on)
Yoshi's Island 3:
Complete the level as usual.
Yoshi's Island 4:
Complete the level as usual.
Iggy's Castle:
Complete the level as usual.
Donut Plains 1:
Here is the tricky bit. Grab a cape and fly. You'll eventually see a green pipe. Once you pass it stop flying and land on the yellow floor. Hold B and run into the key to pick it up. Keep holding B and bring it to the keyhole to move on.
Donut Secret 1:
Once you see a P block pick it up and swim to the keyhole. Press the P block near the keyhole and grab the new coins. The ? block holds the key. Open it and bring the key to the keyhole.
Donut Secret House:
Make sure you have a cape from Donut Plains 1 and go all the way to the right, through the door and all the way to the left. Pick up the P block, run and jump near the blocks. If you hold A the cape will carry you to a high area. Press the P block up here and a door will appear. Go through it and defeat the Big Boo (grab the exploding blocks by pressing B, hold up until the Big Boo appears and press B again to throw it.) to exit. Once out use the star road teleporter to reach Star World 1.
Star World 1:
Fall through the gap at the beginning and run to the far right. Spin jump (R) to reach both the key and the keyhole.
Star World 2:
When you reach the green pipe swim under it to reach the key and the keyhole.
Star World 3:
Use the Big Boo technique to knock Lakitu out of the sky at the beginning. Then hop into his cloud and go up to reach an area holding the key on the left and the keyhole on the right.
Star World 4:
Either grab a cape (Donut Plains 1) or a blue yoshi. (Star World 2. Feed the baby yoshi the falling star at the beginning) Then fly to the area on the bottom of the screen under 2 green pipes to find the key and the keyhole. Once out of the level use the star road teleporter.
There you have it. You're at Bowser's front door. Good luck!
