Setting up NSMBe5 on Linux

If you are considering swapping to Linux (or are already using Linux), modding NSMB DS is still perfectly doable! NSMBe just needs a little bit of setup before you can begin opening levels. After this tutorial, you'll be up and running with NSMBe on your favorite Linux distro.

• This tutorial has been tested on the following operating systems: 
  - Fedora
  - Manjaro (should work for every Arch-based distribution)
  - Linux Mint (should work for every Debian-based distribution)
  Help us improve the compatibility list!

Requirements:

• A computer running Linux
  
• The latest build of NSMBe5

While not needed, having administrator permission (sudo) is helpful for troubleshooting

Step 1: Installing PortProton

Method 1: Via Flathub (recommended)

Follow the Flathub setup guide. Then, install the app by opening a terminal and typing:

flatpak install flathub ru.linux_gaming.PortProton

If it doesn't work or you need admin rights, check the second method.

Method 2: Manual installation

Go to flathub.org/apps/ru.linux_gaming.PortProton and hit “download”. This will download a .flatpakref file.

The file should appear in your Downloads folder. If your browser asks you where it should save it, choose a location that you will remember.

Go to the file's location, right-click an empty space, and select "Open in a terminal". From there, type the following command:

flatpak install ru.linux_gaming.PortProton.flatpakref

If it doesn't work because admin rights are needed, try the following command instead:

flatpak install --user ru.linux_gaming.PortProton.flatpakref

If this method still doesn't work, ask us in NSMB Central.

Congratulations! You're now ready to open NSMBe!

Step 2: Installing NSMB Editor

PortProton might download some files before starting the first time you launch it. That's normal.

Go to your NSMBe5 folder. Open NSMBe5.exe by double-clicking on it. You should see a window like this:

Make sure to change the prefix to "DOTNET"

If you want to add a shortcut to your app menu, click on "Create shortcut". It will ask you where to put it:

Once it's done, click "create shortcut".

Now, to launch the app, just have to click on the "Launch" button, and there you go!

Congratulations! Now, you are ready to make awesome stuff with Linux!

FAQ / Troubleshooting

Some actors appear weirdly, how can I fix it?

When opening a level in the level editor, some elements may seem scaled incorrectly:

This is because your computer is using fractional scaling. This zooms your screen, but not all elements in the app. To fix that, go into your display settings and select 100% or 200%:

Now it's working better!

No better solution has been found yet. If you have one, please tell @rph_nsmb on the NSMB Central server.

It takes a while to navigate with the file explorer. Can't I add a shortcut?

Of course you can! First, you will need to go to the parent folder of the one you want to make a shortcut (for example, I want to add /home/rph/Documents/Template, I'll go to /home/rph/Documents). Right-click on the folder you want to make a shortcut and select "create link". You should see something like this:

If you don't see the "Create shortcut" option, take a look at the file explorer's menus or check its settings.

 Right-click on the link and select "cut".

Now, you will need to go to your PortProton setting folder. To do so, go to your home folder and go to PortProton/prefixes/DOTNET/dosdevices. Now paste your linked folder and rename it to a lowercase letter followed by a colon, for example: n:.

Now, if you open the file explorer, you should see your drive in "Computer":

Congratulations! You have your shortcut.
