Xbox’s new backwards-compatible games on PC are “already Xbox 360 games” — and that changes everything about what’s next
If you’d asked me a couple of days ago, before Xbox’s latest news, what games had me excited about PC gaming, there’s no way I’d have named BLiNX: The Time Sweeper, Conker: Live and Reloaded, Crimson Skies: High Road to Revenge, or Fuzion Frenzy.

What I’m up to this week: Other than settling back into work after a couple of weeks of dealing with a flood, I’m enjoying summer weather to catch outdoor concerts and to catch up on guitar practice.
Alas, here we are. These four classic Xbox games are spearheading the new Xbox backwards compatibility program on Windows PC, with more titles expected to arrive in the future.
Sure, this initiative might seem small today. These are four first-party games without many legal complications. A toe dipped in the water, if you will.
But new information about how Xbox is handling backwards compatibility has emerged since the news first broke, and it has me rethinking the entire situation.
The back-compat OG Xbox games just released on PC are already Xbox 360 games
Over on the ResetERA forums, a software and netcode engineer known as Edward850 — who I think was also a developer at Nightdive Studios at one time — began commenting in the backwards compatibility discussion.
Responding to another person’s optimism about Xbox 360 also being a possibility for backwards compatibility, Edward850 revealed that they’d done some digging into the tech behind the program.
It turns out, according to Edward850, that the four Xbox games kicking off the back compat program are “already 360 games.” Inside the game files, it’s evident that Microsoft is using the Xbox 360 Xenon Fusion (XeFu) emulator to run the games.
As X user @TheLunarixus notes, this is confirmed by “XEX2/STFS magic and strings in the kernel such as “XENON KERNEL EXITING.“
Fun fact: The new OG Xbox Backwards Compatibility layer released by Microsoft for the PC is actually an Xbox 360 emulator running Xefu (the OG Xbox emu for the 360), confirmed by the XEX2/STFS magic and strings in the kernel such as “XENON KERNEL EXITING”. Crazy.July 22, 2026
As far as I can tell, this means that Microsoft isn’t emulating the original Xbox directly. It’s emulating an Xbox 360 that’s running the 360’s built-in Xbox compatibility layer on top.
The rabbit hole goes deeper. This is the same sort of wizardry that allows original Xbox games to run on the Xbox One’s x86 architecture via layers of Xbox 360 architecture. It’s a convoluted way to reach an end goal, but hey, if it works, it works.
This information is really what got my attention. If the foundation is already a working Xbox 360 emulator, 360 games being backwards compatible on PC is more than plausible. In fact, it’s probably already almost ready for primetime.
The likelihood of Xbox 360 games on PC just got a lot better
The core statement that “Microsoft made four old Xbox games run on PC” gets a lot more exciting now that I know how everything works. The four OG Xbox games look a lot more like the tip of a much larger technical foundation that’s already capable of running 360-era games.
Correct me if I’m wrong, but the hardest part about console emulation is the base architecture rather than the games that run on it. So if the base is already capable of handling Xbox 360 games, the path from four OG Xbox titles to a plethora of 360-era games is a lot shorter than it seemed just a few days ago.
The Xbox 360’s library is what really gets me excited. I wasn’t much of an OG Xbox gamer (I was too busy with PCs), but I had a lot more experience with the 360. It’s the generation that landed right when I was graduating high school, and I know I’m far from the only one who considers its library of games to be peak.
If Xbox 360 emulation is indeed on the table, Microsoft’s back-compat news stops being a nostalgia play and instead becomes one of the most significant moves Microsoft could make, not just for Game Pass (on which these games are launching), but for game preservation in general.
I don’t know how this all relates to Xbox’s “Positron” disc-to-digital program, but I can’t imagine the two initiatives won’t collide at some point.
Microsoft hasn’t yet made anything official, but I’m feeling hopeful
Let me be honest here. Microsoft has been pretty quiet about what’s going on behind the back-compat scenes. There’s no roadmap, no announced Xbox 360 support, and no timeline for any of it.
The information I received could be wrong (not likely), or Microsoft could have reasons involving licensing, resources, or other priorities that keep it from acting on the Xbox 360 capabilities, even if they do exist.
It’s worth pointing out that my colleague, Jez Corden, has teased that there’s “more to come” regarding the back-compat program. He knows a lot more about Xbox than I do and generally has plenty of inside information he keeps close to his chest, so this comment could certainly give away a lot more than it does at first glance.

In any case, Xbox seems to be making all the right moves at a time when game preservation is a hot topic. Microsoft might have just flipped the switch on one of the biggest customer service endeavors in video game history, and I can’t wait to see what the future holds.
