Basically, the games that allow button remapping don't allow you to remap the ZR and ZL buttons. The C-Stick cannot be remapped either, and there seem to be no plans from the developpers to add support which leads me to think that it cannot actually be done at all.
Is there some specific reason for this? (I mean is it something hardware-related or similar?).
