I need help learning sysmodules

[Estym]

Hi!

I'm currently trying to learn how sysmodules works by looking at existing ones to hopefully be able to make some myself.

However, when looking at the codebase of some, I stumbled across the config.json file, which I couldn't find any documentation on what it does, mean, well pretty much anything about it.
If anyone has any information about what it is and how to make one with details about each field, I'd love to learn about it!

Also, I tried to compile and run the sys-hidplus sysmodule myself, but couldn't get to run the nsp successfully on my switch, I'm currently using GCC to compile as well as the latest version of libnx, and I have modified the main.cpp to use the new hiddbgInitialize‎ signature, it compiles but does not run. However, the released nsp does work flawlessly.
If anyone manages to compile and run this submodule I'd love to learn how you did it!
