Hi guys, I've noticed that there weren't any videos about this yet, many were saying it wasn't possible, some people simply didn't want to show the process, but I'm here to help!
Shoutout to femboypumpkin4530 for the mod :D

Before getting started make sure you're on the correct version of the game, on the latest luma version, your plugin loader is enabled and ensure you have custom firmware installed. (I forgot to show the plugin loader step in the video I'm sorry!)
In case you haven't done this yet, make sure you enable "plugin loader" from the home screen of the 3ds.
To do this, press "L + Select + Dpad Down" at the same time and the menu will pop up, scroll down the options so you can enable the plugin loader!
It turns out the mod works on all versions of the game EU/NA! Just make sure you create the correct folder for your version. Make sure you read the descriptions to ensure specific mods are compatible though.
Quick note:
After creating the luma folder titled "000400000008C400" with the OnionFS.3gx file inside of this folder (around 3:10 of the video) I instruct to remove the SD card from the computer and reinsert into the 3Ds where I go through opening up OnionFS through Tomodachi life for the first time, This step is to ensure that OnionFS will actually run and creates the necessary files, but Technically you can create the OnionFS folder on the root of the SD card manually, before taking out your SD card.
- To do this, create a folder on the root of your SD card and name it "OnionFS ," inside OnionFS you make another folder, name this one according to your version, but its NOT the long string of numbers, its either 0008C400 (for Europe) 0008C300 (for North America). Inside the 0008C400 folder you make two more folders; one titled "romfs" and another titled "save." Then you can copy and paste the contents of the romfs you have installed into the romfs folder in the SD card. Then you should have everything set!

If you'd like to transfer your data to another version, for any reason I highly recommend a save editor.
A good save editor:

You can also use some mods together, by merging files (putting contents of one mod into another) but if the file manager tells you that there are files of the same name, it's likely the mods would conflict.

If you need to extract files you can use 7zip or winrar!
