Thanks for your responses. I was concerned about being unethical or illegal by using someone's intellectual property without paying for it if the license would require it. This came to mind even more when I see that Mighty Mike appears to have run crosswise with the evil empire over his WM 6.5 ROM. So if I understand correctly, everything in these ROMs is in the clear with the licenses, and all I have to do is get over my hesitancy to dive in and risk a brick. (Fortunately I've read enough to realize that things can be done to overcome when things can go badly.) Thanks for your help.
