Koopa Staircase Trick

The main point of this trick is the timing of the first jump, if success, press A button (jump) once, the shell will bounce to the block repeatedly, and Mario will jump automatically. If Mario stop jump, press A to initial the jumping sequence again.

Try keep the total number of lives less than 128, if the lives go above 127, the game will be over next time Mario dies.

BIG Mario is easier to make the trick success.

It is said that this trick can be applied at the end of World 3-1, 5-1, 5-2, 6-1, 7-1, and 8-2. I have not tried all the world, but World 3-1 and World 7-1 is ok.
