I made a Doom source port that runs within a PDF file.
PDFs support Javascript, so Emscripten is used to compile Doom to asm.js, which is then run within the PDF engine. Input/output is done by manipulating text input fields.

I got Linux running in a PDF file using a RISC-V emulator.
PDFs support Javascript, so Emscripten is used to compile the TinyEMU emulator to asm.js, which runs in the PDF. It boots in about 30 seconds and emulates a riscv32 buildroot system.

Had to pop out last night, yet managed to get Speculation running online using Emscripten before I went to bed. Was an additional half-dozen lines of code and took me about 10 minutes. Emscripten is nothing short of witchcraft.

Tinkering with Box3D + Sokol + Emscripten :)
Box3D is *fun* to work with, very simple and straightforward C API, and very configurable (this is simd + single-threaded).
New sokol-sample will be up in one or two days.
