SMM2LevelViewer VS MDE

Super Mario Maker 2 is a good example of accessible level creation, but for other players the levels themselves are black boxes. Yes, it's easy to create and upload levels, but downloading and viewing other people's levels in the level editor is simply not allowed on a standard Switch. This is a problem since levels in general are not WYSIWYG: they use e.g. off-screen mechanisms, hidden blocks, and overlapping entities.

It took over two years before 3rd-party software could break Nintendo's DRM and give players the privilege of seeing how someone else's level works:

and even that effort only evaded a ban for a month or two:

The error I get has already been raised as a ticket

Doom is such a great learning tool. If you have any interest in DOS games and programming, grab a copy of the Doom specs and start plugging away at the WAD file

You can use any language you want to work with the data, but C is probably the most straightforward. The first time you decode some sprite data, or a level map, you will have the strangest sense of joy as it appears on screen.

I used to play around with that stuff in the 90's with a copy of Turbo C and started to write a Mac level editor (very simple one at least) a few years back but haven't really worked on it since I had kids.
