I was thinking of making a joystick that would support both Playstation and Saturn. I would use these mainly because I can go from Saturn and then convert to Dreamcast using a converter and everything Playstation output, I can convert to anything else with other converters.
My only concern is how to get this working in the first place. How can the joystick and buttons each send a signal to 2 controller boards without any sort of conflicts or lag?
As anyone tried this before or knows how this would work in the first place?
