I found a program called JoytoKey
has worked out pretty well. You can map any keyboard or mouse input to a controller. In this case an xbox 360 controller.
Once in JoyToKey create a new profile.
First go to others and check Use Axes other than X and Y and Use POV switches. Make sure to put the threshold above 0 (or if your controller is sensitive it can result in an input rather than nothing when your not touching it). I use 10%.
Then go back to Joysticks. These are the corresponding mappings for the 360 controller.
this is the setup I am using in Amnesia with the mouse sensitivity to 3.0 in game. http://www.mediafire.com/?mvmx9cchc82l8l7
If there is a better program out there for doing this type of thing let me know as I would like to do this for other games that dont have gamepad support built in. Or if you find better settings to use with JoyToKey let me know.
