  • >Frankly, writing directly in emojissembly is a miserable, painful slog, lacking reasonable immediate values, arithmetic operations, or sane jump offsets. Therefore it is sensible to construct a loader that can simply build 8088 code in memory and jump to it.

    If you think that self-modifying loader is too easy, I recommend Tom7 take on printable x86:

  • For this to be reproducible the browser version is going to need to be specified.

  • Thanks for checking this out.

    I've uploaded all the binaries to GitHub if you're struggling with copy & paste. There's also a new example in Braille.

  • Anyone managed to reproduce it? I tried copying using Firefox on Wayland on Ubuntu GNULinux, then pasting on a Vim window. Nu luck, md5 didn't match.

  • Waiting for someone to an emoji-x86 backend to LLVM/GCC.

  • Oh this is delightful!

    x86 assembly isn't something I'm familiar with (and I should really get back to $dayjob), but I will mention the existence of emoji-test.txt [1] in case somebody wants to try and mine more executable sequences. It might be worth paying attention to the minimally-qualified, unqualified and component lines, which can be added and removed semi freely. No idea if they actually correspond to useful byte sequences.
