The thing that really gets me about reproductions is that the people making them have a complete disregard for the makers of translation patches. Most of the people who made the translations explicitly state that their work is not to be bundled with a legit copy of the game, patched or not. They also explicitly state that no one should sell their work. Another problem is that a lot of repro makers cannibalize other games to make them, which is completely unnecessary now that homebrew lockout chips exist. Some of the makers of patches have attempted to shut down the repro makers, but there are simply too many to deal with.

Besides, most reproductions are completely unnecessary with the advent of flash carts.
