I have copies of the CRJ FMS trainer, but burning you one would be illegal, right?  : (
The CRJ uses a Collins CDU and the Embraer has a Universal.
Don't get too wound up in learning any particular FMS, they're all different.  I knew less than nothing when I got to the CRJ 700 and  although it was a new concept, the FMS was a breeze to learn.
