Are there any patterns to the power-up panels in the red mushroom houses in New Super Mario Bros. Wii? Is there a way I can tell where the Bowser/Bowser Jr. panels will be?
Each level has 6 different layouts. Once I had those in text form I wrote a small program that generated a PDF based on these. The items with green background do not have any Bowser (Jr) in that world in that position and can be safely clicked (if you know the green patterns, you always get at least 3 items from the red mushroom).
