Whoops. Forgot to convert the existing received friend vouchers for Metroid Prime Trilogy before doing the Wii system transfer, only just now realized that (first time I've started the game in awhile). And since WiiConnect24 does not operate on the Wii U, there's no way to get sufficient Friend Credits to unlock everything there (and of course the game save data cannot be copied off of the system to move to the Wii).
