I am trying to setup my controls in a Guitar Hero PC Clone game (Frets on Fire), but it doesn't support the use of my mouse. What I would like to do is play the game with an emulator that when I click a certain button on my mouse, it presses the set corresponding key on the keyboard. Is there a program out there for XP, that would allow me to do that?
