Highlight 'Options' and press and hold Y, X, and A.
When the options screen appears, let go of X and A but keep holding Y.
Change the energy to max and the difficulty to easy.
Move down and press X on 'Exit'.
Now start the game and select the character using the X button (you should be holding Y all the time from the beginning).
If it has worked, after you select you character the number 1 should appear in the middle of the screen. Now you can let go of Y and use any of Y, X, A to change the level and start to accept.
You can't just skip to 4 and get the achievement unfortunately, so you still have to go through the third level.
