Demo number 7 is not loading for me. It says 'Sphere.smf and ClockTownSouth.smf are not valid .smf files'. :(

Ah, yes, there's currently a bug with GM where compressed buffers won't load in HTML5! I've reported it, hoping they will fix it soon!

Nintendo Switch Game Engines

When reverse engineering games, one of the first things to find out is which engine the game is based on, this will save a considerable amount of time if it is based on a standard engine that is well documented.

This page will list only the confirmed engines for each game along with proof that the game3 was built with that engine, so the list won’t contain every game, but any game on the list you can be confident it was based on the engine listed.

Unity3d has supported the Nintendo Switch right from launch and the dev tools are distributed by Nintendo themselves rather than by Unity. Developers need to have signed up for a Nintendo Developer account to be granted access to download the Unity plugin to allow exporting to Switch ¹.

Reverse Engineering & Modding

Unity3D games are compiled from .net byte code down to C++ when generating a Nintendo Switch version. This makes it harder than standard Unity reverse engineering as the generated native code is harder to decompile than .net byte code.

There are tools than support dumping the data from Unity NRO games such as the Il2CppDumper:https://github.com/Perfare/Il2CppDumper

You should always backup Managed/Metadata/global-metadata.dat as it contains debug symbols for the game.
