I don't know if this is commonly known or not but the "MS Sidewinder Precision Pro" "IS" InputSprocket compatible (I'm using Gamesprockets 1.7.3) in the Input Sprocket dialogue box it allows you to use ALL of the joysticks functions, the Joystick is even correctly named so Apple must have updated InputSprocket to be compatible I guess,
It also seems to work fine with USB overdrive.
I wonder how may other of MS joysticks & pads work?
I know that there 6 button (iMac'ish styled) gamepad is supposed to work with InputSprocket too! (According to the same person who told me that Precision Pro work's).
I'm off to try podracer now , which is supposed to work with this joystick, I know I've partially crossed over to the darkside but hopefully this won't effect my Jedi karma in Podracer.
P.S I've also bought a Intellimouse Explorer, this works ok, but I've actually got so used to the hockey puck that it is actually hurting my wrist using the Explorer!
(it also skips a bit too, apart from that it's okay)
