No, I built it off of krw703's legendary Mega Man X engine (which is essentially perfect). I had to build Zero from X, which was considerably difficult. I can send you that, but you'll have to build Zero from it yourself.
And I hate to sound pessimistic, but depending on what you would do, I might send you the VZ engine. If all you're wanting to do is just add and change a few things and call it your own, I won't. You don't seem like that kind of person, but that's the impression I'm getting from what you're asking. If you really just want to build from it, then I'm a little less hesitant to share it.
