Syntax highlighting for Dream Maker (BYOND) language


Hello, there!
I was searching for syntax for this (really weird and obscure) language called Dream Maker, for which there is an already existing Sublime Text (3?) package, which can be found here:

I was wondering if it is possible to convert or modify the existing syntax definitions for Atom using a converter of some sort, or if I have to make the entire thing by hand.

Thanks! :smile:
