i wonder how performance of this (emscripten of Unicorn) compares with this much more flexible ARM emulator from a few years ago (which I am much more excited to use for things as I can easily customize the instruction fetch and memory access routines; it is even straightforward how to just hook system calls). https://github.com/ozaki-r/arm-js http://biged.github.io/arm-js/arm-js.html ^ The latter link is a demo; click "Boot" in the upper left.
