Tutorials on how to mod NSMB DS
Mario vs Luigi
This page documents how to play MvsL hacks and objects that work in MvsL.
Modding MvsL is significantly more difficult than modding Singleplayer levels. If you're just getting started with modding the game, you might want to start here
FaQ
How do I play Mario vs Luigi hacks?
- The easiest way to play an MvsL hack on real hardware is by using “Multi-cart”
- This requires that you own two flashcards (such as an R4 Card).
- To set this method up, simply put the same ROM on both flashcards. Then, in the game, choose the option to “Compete with another New Super Mario Bros. Owner” and play MvsL as you normally would.
- If you do not have access to two flashcards, then you have two, more difficult, options remaining
- Your first option is to try and use a hacked NDS firmware that bypasses Download Play's signature check
- Download firmware.nds and put it on your flashcard.
- Open this ROM on the DS you will launch Download Play from.
- Now, eject the flashcard from the DS you just ran the ROM on. (This will not cause your DS to freeze)
- Finally, put the flashcard back in the other DS.
- Once you have done this, you can run the ROM of the MvsL hack and select “Play with someone who doesn't own New Super Mario Bros”
- If the firmware ROM does not work on your flashcard, try this one instead.
- Your final option is to use normal DS Download Play with “DLP Mode” in NSMBe 5
- Open a clean (unedited) ROM
- Open it in NSMBe
- After you open the ROM, go to Tools and check “Enable DLP-friendly mode”
- Now, you can make whatever changes you want to the ROM
- When you're done, you can play with another DS through DS Download Play like you normally would using the “Play with someone who doesn't own New Super Mario Bros” option
- Your first option is to try and use a hacked NDS firmware that bypasses Download Play's signature check
- If the game hangs at the Nintendo logo, you might have missed a step. Double check you did everything and try again with another clean ROM
- If the DS freezes with a black screen after you select a level it can mean one of two things:
- Your flashcard is not compatible with this method
- There's something wrong with the level that is making the game freeze
My level crashes, what do I do now?
- If you are not using any Code Hacks, then here are some things to consider
- Have you changed any object banks? This causes MvsL to crash so you need to change the object banks back to whatever the level had originally.
- Double-check that you are not using an object that has been confirmed to crash MvsL. There is a table later on this page that shows what objects are compatible with MvsL.
- Have you changed the number of Battle Stars that are in the level? Changing the number of Battle Stars in a level can cause MvsL to crash, and you will need to restore the original amount of Battle Stars the level had.
My level crashes, but I'm using Code Hacks!
- Even with Code Hacks, not all objects work in MvsL. Take a look at the table at the end of the page to see if all of the sprites you're using are compatible with MvsL.
My level makes us de-sync, what's going on?
- Some objects use RNG to determine their movement and behavior and this value is not synced across the parent and child DS. This causes the object to act differently on each DS, thus causing a de-sync.
Sprite Compatibility Without Code Hacks
- These objects will work in MvsL regardless of if you are using code hacks
- Most of the objects in this list are objects that are already used in MvsL

Sprite Compatibility with Code Hacks
- This spreadsheet is based on the MvsL Hacking Starter Pack
- There are 4 kinds of compatibility
- Works: This object completely works in MvsL
- Partial: Some parts of this object do not work in MvsL. The notes column will mention what doesn't work
- N/A: The object does not load but it also does not crash the game
- Crash: The object crashes the game when loaded. See the notes for possible workarounds.

Modding 101 - Creating a Bare-Bones Level
Welcome to the world of New Super Mario Bros. DS modding. Making your first level is the first step every modder takes when starting from scratch.
In this tutorial, you'll learn how to:
- Install the necessary tools to start modding
- Open your ROM in the editor
- Open a level from your ROM
- Create a bare-bones level to build from
Section 1: Getting Ready
To edit the game, you'll need a copy of your New Super Mario Bros. DS ROM and the New Super Mario Bros. Editor (NSMBe).
We are not allowed to give a download to the ROM. If you have a 3DS, here is a guide that lets you dump your game cartridge ROM using a modded 3DS.
For the best compatibility for more complex tasks, you will need a US region ROM.
Head over to GitHub to download the latest version of NSMBe from the Mamamia Team. When you click the link, you will be taken to a page that looks like this:
Just click on NSMBeX.X.X.zip to download the editor. (The X's will match with whatever version the editor is on. As of writing this version is 5.4.1, as seen in the screenshot)
Now, in your downloads folder, you need to extract the zip file. On Windows, this is done by right-clicking the .zip and clicking Extract All... Just click extract on the window that appears. You should now have a folder in your Downloads folder named NSMBeX.X.X.
The final folder will look something like this:
You have now installed the necessary tools to begin modding
Section 2: Opening Your ROM
Now that you have the editor extracted, let's open up your ROM!
Inside of the NSMBeX.X.X folder, open the app named NSMBe5.exe. You should see a window that looks something like this:
Now, click on Open ROM... and open your dumped ROM of New Super Mario Bros. DS
The ROM will have an extension of .nds
You should now see this:
You have now opened your ROM in the editor
Section 3: Opening a Level
Now for the fun part, editing a level!
To start, we will open 1-1, Area 1. To do this, open the World 1 drop down, open the 1-1 dropdown, and finally double click on Area 1.
Each level in the game has a various number of Areas. Nintendo used these as a way to keep each sub-area separated. For example, Area 1 of 1-1 is where you start the level, and Area 2 is the bonus room found in Area 1.
You will now be presented with the level view:
If the level view appears too small, you may need to modify the config file. To do this: open the file named "NSMBe5.exe.config" using Notepad, delete the lines: <System.Windows.Forms.ApplicationConfigurationSection> <add key="DpiAwareness" value="PerMonitorV2"/></System.Windows.Forms.ApplicationConfigurationSection> After deleting the lines, save the file, restart the editor, and open Area 1 again.
You have now opened a level from your ROM
Section 4: Creating a Bare-Bones Level
It is best practice to start from a blank level, so let's clear out the existing level by pressing Ctrl+A to select everything in the level, followed by clicking the at the top of the editor window. Your blank level will look like this:
Now that we have a blank level, what do we need to add back?
All levels in NSMB DS must at minimum have a Start Entrance and at least one main View. With that being said, let's add them back!
To begin, we will add the main view. To do this, click on in the sub-menu bar. This will show a list of all the views in the level (or it would if we didn't just delete everything in the level). To create a view, all we need to do is click on Add. Your level will now have a transparent box:
You'll notice a bunch of settings here. For now, the only thing you need to worry about is checking Scroll vertically. This allows the in-game camera to follow Mario up and down inside of your level.
The View defines the bounds of your level. The camera is not allowed to go outside of the current view. Mario can go above the view, however the camera will not follow him. The sides of a view will stop Mario. Mario will die if he falls below the bottom of the view.
Click and drag the small box that says View 0 and move the View to the top left of the level. While we're moving the view, go ahead and grab the bottom right box and extend the view to be one square big. You're level should look like this now:
Now, let's create the Start Entrance. Click on the button in the sub-menu. Similarly to the views button, this will give a list of every Entrance that is in this level. Go ahead and click on Add to create a new Entrance.
Once again, there are a few settings on the entrance that you can play with but for now let's just move the entrance inside of our View.
There we go! We have what's at minimum required. However...if we were to play this level now, Mario would just fall down and die. Let's add a floor and the Goal Pole's Flag to this level!
To get to the Tile picker, click on the button (and also click on Tileset 1 if it is not already selected). Your side bar should now be filled with Tiles!
Go ahead and pick the tile I have selected (highlighted in red in the screenshot), then right-click to place the tile in our view. After this, you can grab the corner of the tile and stretch it out across the view.
Not bad! Now, let's make a Goal Pole for Mario to clear the level with.
First off, click on the button in the sub menu to bring up the Actor List.
This is every Actor in the game. You'll become familiar with more Actors as you begin making levels. For now, enter "Goal Pole's Flag" into the search box. This will now filter out all other Actors.
Click on the Actor in the list, then right click in the level like you did for the tile. This will add the Goal Pole's Flag into the level.
On the left, you'll notice that some options for the Goal Pole's Flag has appeared. All Actors will have an options menu appear for them when they are highlighted in the level.
All that's left to do now is finish tiling the Goal Pole.
Test your knowledge! The Goal Pole tiles are located in Tileset 0, try and build the flag like the next screenshot! Here's a tip, the Goal Pole is 9 tiles high and two tiles wide.
With the flag created, we now need to build the castle. To begin, head over to Tileset 2 and click on the castle. Now, right click to place the castle and drag it to create the castle. Your level will look like this now:
We're almost done. The castle in this game is composed of three tiles: the castle we just created, the wall that will stop Mario, and the roof that allows the small flag to show up after you cleared the level. Select the wall from the tile picker:
Drag this wall over the castle you created.
Lastly, drag the roof tile over the castle like you just did for the wall
You have now created a bare-bones level
You can now save your level using the save icon or by pressing Ctrl+S.
