As far as I know, the -TR Wiimotes enforce authentication now (compared to the non-TR ones) and MS stack just can't pair them correctly, so they don't work. Someone in the issue 5011 also said that a real solution would be writing a Wiimote driver to get Dolphin communicating with it directly, but I'm unsure if a driver would fix this...
