Very easy to replace. Order two of them, since i've read that the itchy and scratchy hole can also go and it's the same switch. You can try bending the Y and it'll work while you wait for the new switch. Mine worked for a lil longer when i bent it, but after a dozen or so games, it started acting up again.
Congrats on picking up TSPP, i recently pick it up also and i love it.
