Overworld Theme from Super Mario World
I am twenty-six years old and just learned that you can replay a castle level in Super Mario World by pressing L & R.

I burned at least fifteen minutes (probably more like twenty) last night trying to get Super Mario World to work. I tried two systems and two cartridges, as well as a few other games, and nothing would work.
I ended up buying it on Virtual Console since I had some money left on my account. It’s weird playing it with the classic controller but I guess it’s the only option I have.
