Unlike Java, C# supports a lot of C style constructs like pointers (provided 
that your code is marked unsafe) and the like that make it much easier to 
port code over.  However, the MAME/MESS 6809 core is very macro heavy and 
you would essentially have to rewrite the thing. 

If I were you, I would leave the CPU core in a seperate module as native C 
code and write your C# code around it, invoking the core through interop.
