On the other hand, how the heck are they claiming to own any of that if they can't even produce the paperwork. A big enough developer would be able to remaster the game just enough to provoke a lawsuit from the "rights holders" and that would be the place to cross-check whether there's any meat in the deal. If they can't prove they actually own the rights, they can't sue. If they can, then they can sell/license it to the developer. Obviously this won't work for a small, independent actor because it's all going drown in the noise of legal billing.

I've always maintained that if we must have copyright then it should be something like a trademark where you have to actively defend it to keep it valid. If you have the "rights" to a piece of music, movie or game then, to validate the copyright's original purpose, you will have to actively exercise those rights to make gains from the "intellectual property". Copyright does not promote innovation if you're not required to gain from your creation: if you're just keeping your work in a drawer there's no point in granting you a temporary monopoly over the right to copy the work.
