Anyone with any interest in the topic of abandonware should go take a look at Ross Scott's channel, Accursed Farms. He has spoken at great length about this stuff for years, and even has a series called "Dead Game News." If you get in touch with him, he might actually be able to help you figure something out for getting the Battle for Middle Earth games running. He's gotten much older, much more obscure games than them running before. His "Games as a Service is Fraud" video is particularly instructive.
