I wouldn’t worry to much about that. Microsoft can build out additional emulation to support those games. Now how much of they can pull from what’s been done with Xbox One / Series that remains unclear.

They can always “borrow” from the foss community and just use their emulators.

I wouldn’t expect the same upgrades you saw with the old back compat catalogue. But hopefully it’s as functional as it was on its OG hardware.

But whatever they do I know the community will be able to improve upon for the whole PC space to utilize without needing to pay Shitsoft for it …
