Description Julian Raschke 2007-08-14 15:51:34 UTC 
Hi,

the OS X/Darwin coolie hat code assumes that all hats start at 0 and go to either 3 or 7. I have a gamepad that reports the range as 1 to 8. It can be made to work by subtracting 'min' from the reported element value, then switch()ing on it. Also, the checks for a 4- or 8-way coolie hat need to be changed from
if (max == 7)
to
if (max-min == 7)
and the same for 3, respectively.

Of course, I can't guarantee that this will break an even more exotic gamepad (one returning wrong min/max values) — but for mine, it worked.
