Just a casual play-through of Super Mario Brothers 3 here... nothing suspicious going on... nope! Nothing at all! Okay, to explain, certain cartridges of Super Mario All-Stars were made with the debug mode feature of SMB3 left on by mistake, and I happen to own one of these cartridges. This allows you to cycle powers and kuribo shoe at will, and thus, antics ensue! Not much in terms of skill going on here as I was just having fun messing around.
