A tool to edit many formats of Nintendo Switch, 3DS and Wii U.


This tool is now archived and no longer in development!


Keep in mind this tool is still very experimental. If something breaks from a commit, you can download manually from here. Just select a commit, go to artifacts tab and download the zip. Also be sure to report anything that breaks to issues here on github.



If you'd like to support me, you can donate!

    • Material copying
    • Animation and model sub section can be exported / imported
    • Can delete, add, replace individual objects from an FMDL
    • Can create new sub sections and data
    • Can preview skeletal, SRT, param, texture pattern, and bone visual animations. (param animations vary)
    • Can export and import fully rigged models with bone support

Issues or Requests


To build make sure you have Visual Studio installed (I use 2017, older versions may not work) and open the solution (.sln), then build the solution as release. It should compile properly on the latest.

In the event that the tool cannot compile, check references. All the libraries used are stored in Switch-Toolbox/Lib folder.

Also, while compiling, Visual Studio might throw errors about files coming from external sources (ie. the web) and will therefore fail to read and compile them. In this event, go into the project root folder and run: Get-ChildItem -Path "C:\\Full\\Path\\To\\Folder" -Recurse | Unblock-File.
