aaaaaand problem solved. Having JUST the prc_race and prc_2das haks associated, plus the custom tlk, gets it working right.
I did not see anywhere any specific instructions about what haks to associate or not so I had to figure this out by trial and error. I did see references to a readme file, which as far as I can tell does not exist anywhere in any of the archives I downloaded. So that might be something to clarify.
