Yes. We are looking for people to help us port the stages over. For a tutorial:
How do I convert a Wii U level to a Switch one?
Switch levels work differently in that instead of being split up into 3 separate files for each list (Design, Sound, and Map), they combine each byml into one archive with the suffix discarded. The other difference is that the endian has been changed from big to little, which adds some extra steps.
To get started, you'll need to extract each byml (by right-clicking and selecting
Export Raw Data) from all 3 lists, as well as
At this point, you should have 4 bymls in a folder -
CameraParam.byml. One way of converting these to little endian is to use Switch Toolbox's converter. Hit
Tools > BYAML > Convert to Little Endian, select a byml, and save it with the same name in a different folder. Repeat this for each one.
Now that you've got the bymls converted, all that's left to do is replace the ones in the Switch level file. Open the szs in Toolbox, and for every mentioned byml inside, right click and press
Replace Raw Data, and select the converted byml with the same name. Once all of them have been replaced, simply right click the szs at the top of the tree and save it into your Switch mod folder, making sure to select Yes when it asks if you want to compress with Yaz0. After all of that, the level should now be in the Switch format, and you can now play it and edit + save it with Spotlight.
