i did read the readme... and to me it isn't very toony, even when you do switch onto the other settings.
Toon Shading is - Outline, Highlight, Base, Shadow
instead this is - n|a, Shadow, Lighter Shadow, Base
just looks like a 16bit metal effect to me, i know that the Outline is on the way and i do look forward to it so wasn't gonna comment on that ... but its really how many cartoons have you watched which have several layers of shadow and no highlight?
i mean setting 3 is very good for it, but still without the highlight its just not doing it for me.

oh and the Toon Shader does work on the FX5200

i'll see if i can get on my machine later and upload a working example, you just gotta know howto use them
