It works for me. Used the image I downloaded from here for the pi 2 a few days ago. Using the thumb drive transfer method the system sets ownership to root for the transferred roms. If you take possession it works fine. I’ve tried it in all three directories, always said missing files until I chowned the roms. Regardless of the directory you have to take possession for it to work.
