Can a 3rd-party PS1 racing wheel be used for Naomi or Sega Model 2/3? I read those normally run on 3.3v as opposed to the Dreamcast controllers' 5v, but some of those actually have potentiometers for the steering instead of encoders.
Sounds about right. You will also most likely not have any dead zone as I've hacked a couple HKT-7400 Dreamcast wheels for Model 3 and they do not have any dead zones. Only the pots can be a little finicky if not insulated properly.As long as it has pots for the wheel and the pedals, it will more than likely work.
