Mario Bros. is an action platformer game for the Nintendo Entertainment System.

This is a full graphics hack that give Mario Bros. (Classic Serie) a more Metroid-like flavour. It was created in celebration of Metroid's 35th anniversary. Rather than being just a lazy gfx swap, many elements were either created or heavily edited specifically for this hack. The player characters, for example, are completely redrawn. There's also a new title screen and several text modifications to better fit the theme.

Please note that this hack is for the special edition Mario Bros. (Classic Serie) from 1993 that was only released in Europe. For this reason, the game will only run at the correct speed on PAL systems.
FCEUX will play in PAL automatically if '(Europe)' is in the file name.
For an added challenge, play on a non-PAL system. But beware, everything will be a little faster!
