Hack of Super Mario Bros.


This is a classic hack done by Acmlm, the ROMhacker who founded Acmlm’s ROM Hack Domain which is home to one of the most popular ROM hacking boards today.

This hack is complete and demonstrates what a quality hack should be. ALL of the levels in the game have been modified and most of the graphics have been overhauled and replaced.

This is the kind of hack that gets people interested in the hobby, so go download and try it out!

Note: A titlescreen patch fix is available separately here.

A Strange Mario Game

Reviewed By: Kallisto on 31 Aug 2015
  • This was played through the FCE Ultra GX
  • Story-

    Not much to say that it is simply what you have played before in the original SMB1.


    The music showed no signs of issues, and plays like it should, but it does slow down a bit if you have too many enemies on the screen, and also the gameplay slows down as well.



    1.) It does some unique things that you would not expect in a Mario game such a pipes taking you sometimes to alternate world paths, and other times booby-trap warps, but it gives you enough time to avoid the traps.

    2.) No one would notice this unless they failed the level or using savestates, but the enemies actually change almost each time in a few parts of a level, but I cannot confirm whether or not this is actually a feature or an actual bug.

    3.) There is plenty of secrets in this game that will help you along a level such as carefully placed hidden power-ups, and hidden warp pipes that would help shorten the level


    1.) The game can get rather buggy, but not enough to be a showstopper. Particularly, the enemies would sometimes be held in place until after a couple of seconds, but other times they will not move at all. This can be beneficial for some levels, but horrible for others.-Bug Report

    2.) One of the levels in world 2 has a springboard at the end that would on a rare occasion trap mario in place if the graphic itself disappears suddenly.-Bug Report

    3.) The game relies a lot on pixel perfect jumps, and I found myself having to use the savestate a lot for some levels of the game, but not all levels would have this problem thankfully.-Gameplay Issue

    4.) On a rare occasion there are booby trap warp pipes that would just make you lose a life, and I found this to be a rather cheap shot against the player.-Gameplay Issue


    Nice use of other classic sprites from other Mario games, and edited to fit the theme I believe he was going for in this game. Some graphics do look original such the ground blocks, and other surprises. Occasionally I saw a few corrupted graphics, but it was rarely ever seen, and usually very minor.


    I would say this game is best suited for people who are moderately experienced, but newbies at Mario should not have too much of a problem playing this if they take the time to get used to the author’s gimmicks.
