How Come Nintendo Does Not Take Steps Towards Legitimizing Nintendo Emulators?
Emulators developed to play illegally copied Nintendo software promote piracy. That's like asking why doesn't Nintendo legitimize piracy. It doesn't make any business sense. It's that simple and not open to debate.
People Making Nintendo Emulators and Nintendo ROMs are Helping Publishers by Making Old Games Available that are No Longer Being Sold by the Copyright Owner. This Does Not Hurt Anyone and Allows Gamers to Play Old Favorites. What's the Problem?
The problem is that it's illegal. Copyrights and trademarks of games are corporate assets. If these vintage titles are available far and wide, it undermines the value of this intellectual property and adversely affects the right owner. In addition, the assumption that the games involved are vintage or nostalgia games is incorrect. Nintendo is famous for bringing back to life its popular characters for its newer systems, for example, Mario and Donkey Kong have enjoyed their adventures on all Nintendo platforms, going from coin-op machines to our latest hardware platforms. As a copyright owner, and creator of such famous characters, only Nintendo has the right to benefit from such valuable assets.
Isn't it Okay to Download Nintendo ROMs for Games that are No Longer Distributed in the Stores or Commercially Exploited? Aren't They Considered "Public Domain"?
No, the current availability of a game in stores is irrelevant as to its copyright status. Copyrights do not enter the public domain just because they are no longer commercially exploited or widely available. Therefore, the copyrights of games are valid even if the games are not found on store shelves, and using, copying and/or distributing those games is a copyright infringement.
