Maybe the WASM files should be compiled from devilutionX project which is based on SDL2

In order to sort out the dependencies issues better, maybe it will be best to compile the WASM files from the https://github.com/diasurgical/devilutionX/ project which has support for SDL2 and Emscripten supports SDL2.

It would need a rewrite either way, since JS needs a centralized event loop, and that project still has lots of modal dialogs and other states like the original game. And I prefer having more control over how things are connected to JS.

The guys from devilutionX project are fine with supporting Emscripten in the future as a target platform, it's a lot of work but it can be done.

Well I already made mine so it would be too much of a hassle.

Besides, from what I understand, SDL support is mainly aimed at producing a complete HTML page with all the glue code, so adding any additional JS-side functionality (such as touch support) would be difficult.

I think devilutionx is already working on touch support.

I'm going to close this, as devilutionX seems far away from being able to compile to emscripten, and I like the way I have set it up right now. The main drawback is broken network code, which I may or may not fix in the future.
