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.

What a Graphics and Music

Reviewed By: The Great Brazilian on 19 Mar 2023

The game is even better to play with your friend, because it has stages that you can get stuck. But it’s amazing to see how well these graphics blend well with the SMB1 Original, and it’s very satisfying with the music from Gameboy Super Mario Land.

Version 1.1 Recommended - Yes
