I'm wondering if it would be worth it to buy the XB1/XB360 backward compatible version just for practice to get the levels down? I own it for pc but my girlfriend uses it for LoL and other stuff so I can't play it all the time.

Hey guys I'm new to running SMB and I've checked out a couple of the videos that are posted but one thing I've noticed is that the "A" "S" keys trick is super useful. I'm using an Xbox controller since it feels more natural to me but I don't see any way to switch the bindings on my controller and it's extremely clunky to have to reach away from my controller and hit A on the keyboard. I want to change my "X" button my controller to "A" on my keyboard and the "Y" on my controller to "S". Do you guys know of any way to do that?
