Title. It's too unfair to everybody else.

like the controller?

Yes.

can you elaborate why?

It's not a way to play the game that the developers intended. It's basically the equivalent of using a turbo controller in an SMB1 run. And as I said before, it's too unfair to everybody else. I shouldn't have to buy a 3rd party controller just so I can get a speedrun record.

Yeah, Wave birds are just wireless controllers, they don't really give an advantage
