Well, in an oversimplified way, yes, but I'm also trying to take that
information and recompile it in to another native machine code.

That's one of the next steps - automatically identifying "procedures" and
making function calls out of them. There are a lot of addresses that are
pushed to the stack that aren't a requirement to run, but a lot of these
old games monkey with the stack pointer and the data on the stack to get
it to jump to other locations, and that's a hard thing to detect and
replicate.
