Extra Mario Bros.

Hack of Super Mario Bros.


New maps, new graphics, new enemies, new powerups, new physics, new final boss. It’s inspired by Metroid and in fact, some tiles are imported directly from it. It’s practically a new game.

Extra Mario is among the top 1% of rom hacks. The graphical overhaul is spot-on, introducing SMB3 and Metroid sprites into SMB1. The music is engaging and moody.

The gameplay is what sets Extra Mario apart. Instead of simply moving left to right, finishing a level and moving on to the next, Mario must navigate through 5 distinct areas of the world via warp pipes. The game only allows left to right movement, but that restriction adds to the gameplay, ramping up the difficulty a few clicks.

The available power ups scattered through the 5 areas create a rich game experience, opeinging new worlds and aiding Mario in his quest to retrieve 8 keys and defeat Bowser.

And the final boss fight… yowza.

There’s even a game+ option if you still want to explore the world after defeating Bowser.

Extra Mario is, if not the best, among the top rom hacks. I can’t recommend this game highly enough. Two thumbs up, five stars out of five. Extra Mario is one of the better games for the NES period.
