AutoHotkey: open-source utility to remap gampad input to button input

Please check here for the program.

Below is a sample script to translate both gamepad axis and button inputs.
========

; Autohotkey Script that matches a few joypad buttons to keyboard events
; Instruction:
; 1) Identify the Joypad buttons that you want to use
; The sample script at
; http://www.autohotkey.com/docs/scripts/JoystickTest.htm 
; provides a good way for you to find out the mapping
; 2) Modify Part 0 and Part 1 accordingly.
; 3) Enjoy!

 
#Persistent  ; Keep this script running until the user explicitly exits it.

; Part 0: turbo key config
; State if any keys need turbo ('Y' if needed)
