Super Mario Bros. is a platforming game for the Nintendo Entertainment System released in 1985. When Bowser invades the Mushroom Kingdom, it's up to Mario to stop him and save the Princess.

This hack updates the entire Super Mario Bros. game to match the look of more (relatively) modern Super Mario games, particularly Super Mario World. With the exception of solid background tiles, every tile has been updated including enemies and power-ups. However, nothing has been moved or had its behavior changed, and all of the graphic changes are simply updates (as opposed to replacements).

The changes were originally kept simple so that it could be used with other level hacks.

The Luigi game from YY-CHR has been thrown in giving the player the choice of using Mario or Luigi (instead of 2 players). This is the only functional change (improvement) to the game.
