It only works if you have an ARM CPU with an NPU.

No, it works on x86-64 assuming the device has a sufficient NPU. Both AMD and Intel CPUs latest CPUs list the Recall preview as available now.

Sure, a subjective 4-part test to determine whether the content is fair use or not. Totally not murky.

You probably did but, there are two Nvidia entries. I’m assuming you downloaded the one under Modern GPUs because it makes sense for your main PC, but a GTX 970 would need the entry that is under Older/Legacy GPUs.

Correct, but that is why there are two different Nvidia images, bazzite-nvidia and bazzite-nvidia-open. OP just needs to use bazzite-nvidia for the older/legacy cards.

Most computers firmware can store a Windows executable. Microsoft pushed for an addition to the ACPI tables called WPBT. That stores a Windows exectuable in the firmware. It is of course totally used for the intended purpose…

If I were to speculate, they are waiting for the NVK (Open source NVIDIA driver) to be more mature. So, they wouldn’t have to release two versions and wouldn’t depend on NVIDIA to update their driver to work with software the Steam Deck uses. I.E. Steam Deck uses gamescope for everything outside of Desktop mode. NVIDIA’s driver didn’t work with it until 2 months after the Steam Deck release. Even though it had existed for years prior.

This doesn’t contain the game code either. It takes a user-supplied ROM and converts it to an executable. Nintendo do not own the code that performs the conversion.

IIRC main Fedora used to not do this until some update crashed people’s sessions including the update process which left their install in an unbootable state.

The ostree based versions like Silverblue avoid this by their updates not touching the running system and instead creating a new folder structure with the updates applied that will be booted into on next boot.

I just use the Firefox flatpak from flathub.

Definitely a strange choice for a distro that pushes flatpak to not use it for the browser by default.

See https://wiki.winehq.org/FAQ#How_good_is_Wine_at_sandboxing_Windows_apps.3F from their FAQ

Are you referring to the ones with excessive sandbox permissions that flathub allows by default? Or is this something else?
