Stack Smash are a team of editors who customise their own textures for the characters and stages of Smash Bros Brawl on the Nintendo Wii (I recommend checking out the rest of their site for some great edits).
Here, they changed the stage to look just like classic NES Mario Bros, even down to the 8-bit tone colouring of the characters.
