Did you know this? Apparently if you bought a copy of Super Mario Bros. 3 in the US, depending on when you bought it the "bros" in the logo is either aligned left on the label or right.
*If the logo on your cart is aligned right, you can't get a world record under current strategies.*
And until *last year*, nobody realized this was a problem. It was believed the versions were functionally identical.
