To save your score, lose all your lives and say no to the continue screen. After that, you will be given a password in which you can continue your game with however many stages you cleared and the score you had.
In the second stage after the chandeliers, there will be a crate. If you push it all the way to the right, then the graphics will start becoming blurry and you won't be able to progress past the boulder lift. The only way to get rid of it is to lose a life or turn off the game. The only harmful effect is losing a life to get rid of it.
In Level 2, after the stage with the chandeliers, jump over the fire and you will get to a part where there are two stones and two boxes. Smash the stones with Wakko and pull back one box with Yakko. Now, make sure that the second box is where you it was when you smashed it. If you walk all the way to the right and then back, the other box will disappear! It doesn't hurt the gameplay since you can still do whatever the game asks for with one box.
To get the box back, just walk all the way left and back.
