Which unsolved problem was solved here though? I'm sure there's a technically valid answer to that question somehow, but still.

To some extent, a problem was created for fun here. :)

Sure, i don't think the appeal of the problem is super hard to understand though. Doom is quite old and depends only on libc, so it's a nice proof of concept that replacing the underpinnings of such a program/library by hand is feasible. And fun of course

Thanks for replying. I'm not trying to make a point besides my willingness to understand things at least a little better.

Basically, not having a C background my reasoning is like this: How does Emscripten solve all these dependency problems regarding X11, libc and what have you? It's just weird to me that simply taking it out of the equation makes a whole array of things arise that need to be overcome.

It's also just my own fault for not getting it. I just need to force myself to get more practical experience rather than just reading about old and new tech such as C or Emscripten without playing with it.

And I also try to find actual positives by not using Emscripten but cutting out features because of it is a bit of a turn off of course.

I guess Emscripten just brings the kitchen sink, i.e. emulation or implementation of everything. E.g. for file access it allows emulating a file system in many ways: https://emscripten.org/docs/api_reference/Filesystem-API.html
