Super Mario Bros.

There are three different SMB ROMs floating around. One has no title logo (the "bootleg" version), another has the title logo but is trained (pressing Select makes Mario swim), and another has the title logo and is not trained (correct dump). I think the files made with the trained SMB ROM will work with the untrained ROM, but files made with the untrained ROM do not work with the trained ROM.
