The FCEUX NES emulator does away with the normal Super Mario Bros. controls by allowing players to “wield Goombas and Koopas like some sort of Mushroom Kingdom deity, often with amusing, potentially brain-melting results.” Video after the break.

This isn’t necessarily a function of FCEUX, but looks to be a custom Lua script that lets the player manipulate tiles and enemy sprites for originally unintended Mario manipulation.
