Dude, just get a copy from a friend or an abandonware site, or find a legitimate copy on the secondary market. Computer programs are digital, so each and every copy is reference quality. It's not at all like the situation with Star Wars. There is no legal way and no practicable gray/black market way to acquire a reference quality print of Star Wars. We're at the mercy of the guy who owns it. Doom fans are not.
