SMB Special - 35th Anniversary Edition

Hack of Super Mario Bros.


Super Mario Bros. Special is a follow-up to Super Mario Bros, originally released in Japan in 1986 for the home computer market. The game features 32 all new levels, 5 new enemies and 5 new power-ups. Due to limitations of the PC hardware, the game engine was quite poor in comparison to the Famicom/NES original. Most notable was the lack of scrolling; the PC version would instead show each screen one at a time.

This port brings the levels, new enemies and power-ups back to the Famicom/NES engine. Also included are most of the unique background changes and other features not possible with the original SMB engine. The end result is a much more playable game that feels like a legitimate sequel.

A hack many of us had hoped for for a very long time

Reviewed By: hdofu on 31 Jul 2021

I can be said there were a number of rom hacks to recreate the game on the NES over the year and while they were able to for better or worse capture the level design what they were missing was what made Super Mario Bros Special… well special and it was clear that wasn’t going to be a simple task. Special coding would be needed to include the new enemies, the new items and powerups would require special programming, an achievement that can’t be understated.

In similar efforts attempts to recreate Super Mario Bros the lost levels in the Super Mario Bros with similar pitfalls due to its special things too, and even though most of those were overcome ultimately the best solution considered by most people who wanted to play the lost levels on an nes without a disk system was an mmc3 conversion. That couldn’t work for Super Mario Bros Special though as Special was made with completely different hardware in mind.

That’s the background for this hack… a hack that’s been in development for over a decade… and what makes SMB Special 35th anniversary so very special. It takes the levels and reworks them into the Super Mario Bros game engine, adds behavior to allow for the new enemies, new powerups, and game mechanics, and makes it work. As a result, this allows this game to be played in a way it could never be played back in the day, and if there is one downside of this, it somewhat exposes the strange level design choices that were made with a screen to screen transition in mind, but that is neither the Author of this hack or Hudson Team’s fault as it, on the one hand, is preserving the accuracy of the hack, and on the other a hardware limit of the time.

There can be no doubt that if you want to play through Super Mario Special, this is the way to do it. It gives you options to play both with the traditional NES look or if you prefer an altered pallete simillar to the original game.

Definetly give this hack a try, it’s a love letter to classic Super Mario Bros. Maybe someday Mario Bros Special and Punch Mario Bros Special and Donkey Kong 3: Dai Gyakushū may see simillar NES Love, wouldn’t have thought so before seeing this hack, but now I see a determined rom hacker can really achieve the apparent impossible.
