I think you made your first mistake when you decided to do "A full compiler"
instead of a translator specific to your needs.
It looks like you made this choice because it was "the most exciting choice".
This is not a good reason. In fact, I think it is a bad reason.


On the other hand, if you start out doing a translator tool, when
you get done you will have something that quacks like a compiler.
But my gut feeling is that it might actually work this year.


If you start out aiming for a "full compiler" your project might
get canceled before you get done.


I am wondering if maybe there is a 4th option that you
have overlooked. Maybe something that sounds stupid like
simulating the old platform on the new platform?
