How do i play old games like mario brothers online with logitech controler?

hate using the keyboard.dose anybody know of a website that lets you do that|||i dont know how to do that. but if i knew about a website like that, i would be glad to help:)|||As far as I know, it is not legal for any website to make a game like Mario Bros online without Nintendo's permission because it is by Nintendo. This is why there is probably no free website that lets you do that. But this is just what I think. Sorry.
