Finally decided to try this.
Works good so far, but the only problem is, my right thumbstick is stuck pointing up, for some reason which, as you may imagine, makes it impossible to play most games.
I tried rebinding keys, rebooting and whatever came to mind.
I'm using a ps3 pad with motioninjoy + betterds3, btw, as at the moment i don't have a 360 pad handy.
I could just wait to get one (360 pad), but i was wondering if it's maybe something obvious.
Besides, i'm not sure getting a 360 pad would even fix it.
