I am not saying to stop sending some emails around and try to acquire third party IP permissions, but perhaps a contact to the IP rights might come out of the woodwork and speed up the processes if you release what you can while you are waiting.

Since this is mostly for historical interest, note what the IP is and what they do, for libraries, perhaps somebody will find a substitute or a version of library with similar functionality without the limitation. For images/sound just include blank ones of the proper dimensions/length and the same filename, if there is enough interest they can be remade.

Just to give you an idea of of the lengths preservationists are willing to go, people in the retroreversing community they are spending months to years converting by hand opcodes of binaries to annotated assembly or C code that compiles byte identically, a few non included IP bits shouldn't be much of a blocker to retro enthusiasts.
