Super Mario Bro-Op

Hack of Super Mario Bros.



Mario and Luigi have defeated Wario but now the brothers face an even bigger challenge… or at least a taller one: Waluigi! Can Mario and Luigi make it through the mazes and hurdles to save the kingdoms? Probably!

∙ Two Player Co-Op

∙ New graphics, levels and music

∙ Unlimited lives

∙ No 1-up mushrooms

∙ [!]-box removes lifts

∙ 20 coins = Star power

∙ Additional stars in invincible boxes.

Navigate through maze-like levels in The Mushroom Kingdom and Sarasaland. A lot of times you need to hit the boxes with dotted lines to make progress.

The game is made with two player co-op in mind but the game is beatable in single player mode, although there may be some paths that are tricky to reach without a second player.

This game features two player co-op, updated graphics and each world has it’s own overworld music.

PATCH Just patch the original Super Mario Bros. rom with the provided IPS patch.

CREDITS ∙ Levels, music production by NesDraug
