I think there is a typo and it should be : 'By far the most likely reason that header isn't an official Nintendo product'the ROM file for Super Mario Bros. currently distributed on the Virtual Console sports an iNES file header, a format that was first developed for an emulation project in the mid-'90s. By far the most likely reason that header is in an official Nintendo product, Cifaldi says, is that the company downloaded a copy of its own game from the Internet. "Nintendo is pirating its own ROMS and selling them to you!" he said.
no it's correct, it's just a long sentence. "the reason that the header is in the file, is probably because Nintendo pirated the game."
