I have a slight issue with the virtual console version of Super Mario Bros 3.
I get a blue line down the left hand side of my screen (same colour as the sky), and on the right hand side it looks like the game cannot keep up with itself (background disappearing, reappearing in right place.
So far it only happens with this game, i have tried others, but they seem ok.
I am using a 42'' widescreen tv if that helps.
Is this a duff download? How can i fix this?
