I need help with this controller config mfa

My friend made this controller config mfa for me but I don't completely understand it.

I'm trying to get it so when you change button controls instead of using something like "Joy 1" it will instead use something like "A button" I'm trying to make my game compatible with 360 controls and I figure it would be easier to change your controls if you knew exactly which button went where. For example say you want to change controls for Jump. Instead of seeing something arbitrary like Jump = "joy 2" it will say Jump = "B button"

You would really have to take a look at the actual mfa to understand what I'm saying.

I put a link for the MFA, and other data files below. (I couldn't figure out how to attach a file)
