Has anyone tried playing Smash with a Pro controller?

I'm pretty sure the game and save file are seperate, so you can re-download MK8 later when you want to play it again and still have everything unlocked. 

I know but I play MK8 so often so I can't delete it. I'll be getting an external hard drive soon though.
