Super Mario All-Stars / Super Mario World Cheats

In Super Mario World, go to the Special World. If you sit there and do nothing for a few minutes, the Super Mario Brothers theme will start playing! It goes back to the Special World music if you leave the map by any way (going to a level or exiting).

Once you have beaten the final Special World level (Funky), the whole world map (and caves too) will be in a completely new color. Most enemies will now look different too. This looks like Dinosaur Land changing over from "summer like" to "fall like"

Complete teh Special World, then enter the Star Road that appears. The world maps colors will be inverted and some of the enemies will have morphed into new monsters.
