Hey Pauli,

somehow we're replicating our work ;)

Yes, and most funnily: You don't need to actually have a .com file
in there - The operating system checks for the MZ/ZM signature,
and then hands the file over to the .EXE handler if present. Therefore
you can just rename any .EXE file .com and it will properly execute.

Cheers,
Thomas
