It doesn't take a rocket scientist to find that 0.1 percent of the code and figure out what is missing though. Textual scholars have been able to reconstruct entire ancient documents by comparing copies. I agree that digital preservation will eventually be needed. Eventually all discs will fail, whether it is 70 years from now or 100 years from now. Eventually those discs will need to be ripped and their code will need to be preserved. But are emulators absolutely nesseccary for that? No. 

2. Like I said before, in 2074 you will be able to 3D print your own PS1. No emulation required. 

You do realise that you're promoting piracy now, yes?

1. I'm not familiar enough with your history to be able to answer to this properly. If you can provide be me a short elaboration, I'll gladly look into it however. Anyway, if a judge's judgement on a matter isn't the official interpretation of the law and thus effectively the law, I don't know what is. Whether that's the correct interpretation of the law might be questionable of course. Maybe you should have a system for fixing judges' errors, but I'd say that's an entirely different issue. Getting back to the actual emulator topic though: Which copyrighted property do you think emulators are violating?

2. I'm not stupid. I know very well something being illegal has nothing to do with its existence. Laws need enforcement to be effective. Anyway, your arguments 1 and 2 are seemingly separate and seemingly counter-arguments to two different arguments, while I only had one argument. Thus, it seemed odd that you seemed to be countering two different arguments when I only had one.

Public domain. 

1. Google Dredd Scott. 

2. You said that if emulators were illegal they wouldn't exist. Your argument was if  A, then B. Or to put it another way, if A (the ground is wet) then B (it is raining). That form of argument isn't valid though, because the ground could still be wet from some other means, such as a burst damn. Affirming the consequent isn't a valid argument. 

Why is emulation such a huge issue for you? The PS4 uses PS2 emulation, the Xbox One uses 360 emulation, the NES/SNES Classics use emulation.

In that case, why wouldn't you use a software emulator?

Emulation of modern consoles by people that don't own the copyright is a huge deal to me. It enables theft, and like Azuren said, anybody that wants to pretend that is isn't being used for theft is full of shit. The majority of people that use unofficial emulators are theives. Piracy breeds DRM, and that spells the end of consumer rights.
