Hey RustKnight, I've been thinking about this and I vaguely remember that either or both of the 0.50 source or CVS source has an msvc project packaged with them, which you could try opening. I don't know if they are live but if so, they could be good starting points.
Another strategy could be to start with the CVS source since it only relies on SDL, which should be straightforward to set up.
The community version on GitHub uses CMake to prepare makefiles. I wonder if it can produce makefiles for Visual Studio?
These are all just guesses at the moment, I'll need some more time to search around for answers, I'll have a look early tomorrow.
EDIT: in answer to your question, no it won't break stuff. If VS is configured correctly and has all the right dependencies, then it should compile no problems. Getting there will most likely not be trivial, but it won't be impossible
