Super Mario World: Super Mario Advance 2
Get the 8 "Special" Sages:
In the stage Star World 5 on Star Road, near the end of the stage, fly on top of the stone blocks. Run to the end on the left of the blocks and there should be a little opening. You should have all four colored blocks unlocked (yellow, green, red, and blue). Having the cape equiped, jump and hold A. This should slow you down a little so you can get in easier. Run over the colored blocks. Two stone blocks are in the way so just run and press down to slide under. Don't try to go in with a Yoshi, they don't fit in. If you do try you're wasting your time and my time. Use the key at the end of the stage to open another Star Road on the stage select screen which inside contains the "Special" stages.
Beat the Game in 60 Sec:
To beat the game in 60 seconds get yoshi and and don't lose him in any level. Next go to the first castle and beat it in 30 seconds. If you do a menu will come up and say game over. Shut your gameboy off and turn it back on. Go to your file and it will say complete.
Get to Star Road:
You have to get to Donut Plains 1. In that level you will need a cape to fly, and then at the beginning you will need to run and then fly. If you dont know how to fly, run until Mario or Luigi sticks out there arms. Then jump with A. They will fly, and when they start to hold their cape. Press forward and backwards to keep them in the air. Make them fly high enough so you can't see them, and eventually while your in the air you will see a key and a hole. Drop down there by letting go of B. Pick up the key and walk to the key hole. You will then unlock another level. In that level after you find the half-way marker, you will find a coin changer. Jump on it, you will have to be fast to get to the key which is in a ?block. There will be coins that you can pick up which are blocks if you don't hit the coin changer. Pick up the key put it in the hole, you will move to Donut Secret House. In there you will have to get to a door in the beginning of the level, it is easy to find. It will take you to another part of the house, and you will need to find a coin changer which is near the end of the level. Step on it and you will have to be fast to get to the door that has yellow blocks around it. Dont go in it but jump on top of the blocks and jump again to get to a bridge type thing, in which you will see a blue door. Go in it. You will fight a big ghost which is pretty easy and after you beat him a portal to star road will open on the map which is right next the level you were just in.
Re-Enter Castles and Fortresses You Have Already Beaten:
When you beat a castle or fortress, you normally can not re-enter until you beat Bowser. Go to the castle or fortress again and press L + R at the same time.
