The only difference between one joystick and another is what they return
for the different button states - ie, some use the the hihat as joystick
2 x & y axis, some use extra firing buttons by using joystick 2 button 1
and 2, et cetera... They'll all work, but you'll have to experiment to
figure out which buttons return what.

Just out of curiosity, what are the 6 degrees of freedom? I know 5
(north/south, east/west, up/down, ana/kata, foreward/backward {the last
two are time, but people seem to like to think of time as a geometric
dimension <it is, but that gets _very_ confusing>}), but it's VERY hard
to real-time more than 3 (at least the way I'm thinking).

The same thing happens to me (so badly I can't use the joystick with some
games {even with Allegro}), I wonder what it is?
