A while ago I was pondering getting emscripten working under Wine, but realised that it's not quite as simple as a typical program (because Wine relies on being able to just provide a compatibility layer for syscalls, so the compatibility layer for x86 would have to be provided by the port to emscripten).
Seeing this post, I wondered if you'd found some cunning way around this so downloaded the project. No, you've just gone straight ahead and implemented an x86 emulator! Ok, but how is wine able to run on bare metal? Oh right, you've actually implemented parts of linux, including most of the syscall interface, your own executable loader, parts of procfs and assorted special devices! Alright, but (as Alon asks) how does this actually render things? Ah I see, you've implemented your own display driver in Wine which, when methods are invoked, dispatches interrupts to the emulated CPU which then forwards and translates the interrupt to an equivalent sdl call (with opengl working a similar way, but with a dll)! Wow! I only had a quick look so I may have missed some of the detail, but that's pretty impressive. Were there any projects you found particularly useful as a reference when building this (particularly the kernel and x86 emulation)? It mostly looks like original work, which seems like quite an undertaking.
