What exactly changed is unknown, but all -TR Wii Remotes may need additional hardware/software to work with Dolphin. Whereas the standard Wii Remotes and the very first Wii Remote Pluses register as RVL-CNT-01, the new Wii Remotes register as RVL-CNT-01-TR. Unfortunately, shortly after the Wii Remote Pluses came out, a new Wii Remote Plus type appeared. Released only a year after the Wii MotionPlus accessory, the Wii Remote Plus is a Wii Remote with the MotionPlus addon built into the Wii Remote.
