probably a dumb question, but are there any banned third party controllers for the n64 version of the game?

no there are not

although I really don't recommend using other controllers like hori or superpad because they are either hard to hold properly or aren't as accurate in movement like the hori joystick

maybe he didnt think of the 2nd one in first place, but later realized he could add this nice info? and it was/is too important to "edit post"? liking it anyways...
