Final Fantasy VII on the NES? Tip of the iceberg. This site has a massive catalogue of other bootleg, Chinese homebrew carts, nearly all of them based on existing game series or movie tie-ins. Link to the Past on NES? Got it. A Lord of the Rings 2D fighter? Got it. Super Mario World on Mega Drive? Yup. A Titanic platformer for the NES? Got that too, and it's amazing.
