Is there anyway to remap the N64 controller buttons? More specifically the c buttons, so I can play with the camera inverted? or am I just gonna have to get used to it being normal when I switch to N64

Not unless you have an emulator or GameShark, unfortunately.

normal is much nicer when u get used to it but assuming you are coming from switch going between the to versions is a nightmare

if you're on emulator you can just map the buttons to how you want it. i suppose maybe if you were okay with playing on GC on console you could get a raphnet adapter and remap the c-buttons using that. that might actually be better imo if you're coming from the switch and you've been using the stick for the camera. if you're playing on wiivc there isn't a way that i know of to remap buttons.
