I have never done interspecies registration, so my help will be limited there.
But in the interest of mental model refinement, my own doesn't think of getting a hemisphere on a standard mesh, with evenly spaced nodes, as a precondition to registration; rather, I think of it as a step in the registration, or a consequence thereof. Something the user doesn't do, but the registration algorithm does. Typically, when we put surfaces through registration, they are not on a standard, evenly spaced mesh going into the process. (Our preborder.sh script in the Freesurfer to PALS pipeline does downsample first, but this is for other reasons having to do with landmark identification/trimming.) With monkeys, I think we still go straight from native mesh to F99, and if your monkey surface was generated by Freesurfer, Colin can probably point you to David's recent tutorial more quickly than I can, since he's used it. But if you're going from monkey to human, I don't think a tutorial exists.
