The Cosmopolitan build is intriguing but a bit confusing:
```
$ file wasm3-cosmopolitan.com 
wasm3-cosmopolitan.com: DOS/MBR boot sector
```
which is supposedly in APE format. from the readme: “APE is a polyglot format that runs natively on Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS.” not sure how to run this. simply setting the execute bit gives “zsh: exec format error: ./wasm3-cosmopolitan.com”

  zsh currently has some POSIX incompatibility, but you can run it with
  
  sh -c "./wasm3-cosmopolitan.com <args>"
  
  also if you have wine installed or some specific environment, you may need to register the binfmt:
  
  sudo sh -c "echo ':APE:M::MZqFpD::/bin/sh:' >/proc/sys/fs/binfmt_misc/register"

  Same error here. @jart got a patch merged into ZSH, so it’s probably that you don’t have master. It works on modern Bash versions though

Wow. Nice work. Is there a path to get a window/framebuffer from this?

  I saw some example for Windows, but it’s not cross-platform.
