If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjustment bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift the edges of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened.

To walk through the world 4 and 7, you must won the 3rd and the 6th castle with mini mario.

If your on world eight and you are on the castle with bowser's shell for a ceilling and no matter how much you walk you don't reach the door than travel this way. At the beggining of the room I'm talking about walk on the Bottom. If You hear a ding on the next one go to the top then the last one middle. If thats to hard for you or not your problem tell me.

1 method is to go through as many mushroom houses until you get a micro mario in reserve.save the game somwhere. dont use the micro until u reach the boss and kill him same way as level2. If you die just reset and try again

You have to run and jump on his head or if you have flower power you can hit his head many times and then jump and when the machine starts going then just duck down using the down arrow until it stops.

To get threw you must figure out the pattern. It goes like this, In the first setion go through at the bottom, at the second section go through the top, then at the third one through the middle and you have the door to bowser

Try to move around, if you cannot keep turning the game off.

This is the end of the game! There is nothing after, the ony reason you don't have 100% is because you haven't found all the stuff in the castle. I know it's kinda dissapointed me too. And the credits don't play until you found EVERYTHING and get Outstanding in the O.W.L's.
