Well if we're going to dive into morality, requiring me to produce additional pollution and e-waste to run your program when I have a perfectly capable turing machine already is unconscionable.

Nintendo: Put your games on steam. Let me buy them without killing the planet.

Apple: License your damn operating system for running on non-apple hardware. Hell, just let me legally run it in an virtual machine so I can test my scripts on your OS without killing the planet.

I disagree. In my case I want to play some of my legally acquired games in ways that were not possible on the original hardware. High FPS, widescreen support, VR, mods. I also want to play my games in a way that's convenient for me, like not having to hook up my console over its own dedicated HDMI. There's more to emulation than just piracy, it opens up a whole field of possibilities for the software.

I'd say it's morally more important for me to be able to run my games at framerates that don't make me nauseous and/or give me epilepsy as opposed to some overbearing company taking away my basic ownership rights in order to squeeze another nickel out of me.

Even so, there is no difference between games from the 80s and games released last week from the perspective of copyright law, which usually works in Nintendo's favor.

>Emulating a console that already exists just feels wrong.

feelings aren't real, you can do whatever you want in this life! :)
