Like @[email protected] said, there’s a flatpak PS4 emulator that makes it trivial to apply the patch, as demonstrated here.

Cough… Ahem…

I dug this out of my history, and cannot recall if this included the mod or not… However, the PS4 emulator software (I got mine directly from the Discovery app repository on linux (flatpak maybe?)) seems pretty much built for this purpose, and made the patch installation process incredibly easy. It was all built into the emulator.

If the emulator software itself (or the patches it retrieves) were removed, I don’t quite know exactly how to re-host that…
