D'oh! I was somewhere else when I wrote that. :-[


AKAIK (and it's not that much):

a) dreamcast calibrates the center on bootup
b) IIRC, each pedal should output a range of ~2.5 volts (2.3v should be enough); I think one does ~ 0.2-2.5, the other ~ 2.5-4.8.  I don't know the supplied current, but V = I * R.  "The rest is left as an exerise for the student."

A couple things to note: since it's calibrated at bootup, the center volts can be other than 2.5, but the ends still need to be ~0.2v and ~4.8v.  Also, I'm basing this off a couple different gamepads; the dreamcast pedals might be different (but I doubt it).
