While it has no recognized merit in U.S. copyright law, nominally the definition is “abandonware” was sold by an insolvent or defunct owner, and the ownership has not passed on to anyone, and so while it infringes to distribute it, de facto there is no one qualified to bring action against redistributors. So, yeah, this probably doesn’t rise to the standard, though separately Sega is uncommonly tolerant of infringement and they made a ton of early 00’s PC ports.
