At this point I contacted Fayzullin himself, providing him with the files we'd obtained. He then compared this with various pirated Super Mario Bro. ROMs found online and discovered the ROM content was identical.

"There are minute differences between ROM dumps," explained Fayzullin. "Depending on the cartridge version and how it has been dumped.
If you see that your .NES file DOES NOT match any of the ones found online, it is likely to be their own ROM dump. I have cut the ROM content out of the Wii file you sent me and it indeed matches the .NES file found online."
