Perhaps true 4 way controls can only be achieved mechanically, I have limited knowledge of Arcade stuff.

i belive this is the only way ...

as i suggested earlier, it is possible to physically switch from 4 to 8way by loosen the screw on the bottum, but if you want something that can switch automaticly i would suggest something like the ultimarc servostik perhaps, alltho those are quite a lot more expensive than the zippy joysticks (especially if you want 2).
