The rest of the article is mildly interesting, but if you just took the bait from the headline:
On a technical level, Xbox One is essentially a PC using a heavily modified version of Windows, and this software simply translates native Xbox applications into a form that can run on standard Windows PCs
343 just sucks at making good halo stories, great gameplay (on infinite atleast), but they just don't know where to take the story. I was disappointed in 4 skipped 5 and infinite was another halfbaked story that just felt empty.
I couldn't get through Halo 4's campaign when it was released as part of the MCC, nor was I able to get though Halo Infinite's (it wasn't bad, just... meh; nowhere near as good as the Bungie campaigns but not trash either, just not as good). I would still like the option to play Halo 5 on PC just so I have the ability to play the main campaign, plus I've heard it's the best multiplayer Halo? But yeah. Even if I never actually play it, it's nice to have the option.
On a tangential note, I think 343's Halo games would have been considered good if it wasn't for Bungie's Halo. I don't think their campaigns are honestly bad, per se (though again, haven't tried to play H5), they're just bad in comparison to the "OG" games.
Anything that emulates something else is an emulator. That something else could be hardware, or runtime behavior, or services, or a combination thereof. (It could even be a turtle, although we're talking about computers in this case.)
Wine is an interesting example despite that silly backronym that was abandoned years ago, or perhaps because of it. It not only translates system and API calls, but also provides Windows work-alike services and copies Windows runtime behavior, including undocumented behavior. If it were just an API wrapper or "translation layer", a lot of its functionality wouldn't work.
The shape of a business envelope might not be an equilateral rectangle, but it is still a rectangle.
But go ahead and believe what you want. I'm not looking for an argument.
I don't know which one of the ctr games you are referring too, but you might be interested about this one https://www.youtube.com/watch?v=hCwSkmAp7f8, there is an effort from ctr community to port the ps1 game on pc
Why would they, Xbox uses a version Windows and an x86 core + AMD GPU, bog standard parts, bog standard system, it's easier to tap into the windows component on an x86 system and just use that to run the games. Making a proper emulator for games that would otherwise run on the PC natively just wouldn't make sense.
I think this will become true for a lot of the new gen systems in the future (starting from xbox1).
Same for PS4 maybe running easier on OpenBSD/Unix-like systems by having a similar kernel.
