Anyone knows how to remap a thrustmaster dual trigger 3 in 1?

Well, I found this somewhere (^w^)

Ok, this is my third time editing this but I think I got it. Up at the top of the rebinding menu it says something like joystick button 1 with arrows on either side of it pointing out. Click those arrows until you get to the button you want (or you can click the button and it will jump to it.) Now that the button you want reassigned is up at the top between the two arrows, use the 'next page'/'previous page' buttons to find the function you want. Then click on it with the mouse. The button you chose should change it's designation. For example, I wan to remap the left d-pad button. This is labeled as 'Joystick POV left:none' to show that it is unassigned. When it says 'Joystick POV left: none' up at the top, I use the next page button until I find 'F9: adjust laser power' or something along those lines. I click on 'F9: adjust laser power' and the button at the top now reads 'Joystick POV left: F9' and I have remapped the button. Hope this helps.
