Opening a .pkg now offers to install it, the way a .zip does - see the new InstallPkgScreen, which shows what the update patches, what it'll take up on disk (exact, since package contents aren't compressed) and where it's going. The package's PS3-style USRDIR/CONTENT wrapping is stripped so the files land where the PSP expects them, in PSP/GAME/<DISC_ID>. Booting a disc then looks for PSP/GAME/<DISC_ID>/PBOOT.PBP and boots that instead of the disc's own EBOOT, leaving the disc mounted - so the update overrides the files it ships and the disc supplies the rest. The update's DISC_ID has to match; a DISC_VERSION mismatch only warns, since updates do get used with slightly different dumps in practice. Verified against the whole corpus: every one installs, and the digital NP* update/base-image pairs that could be assembled all boot the patch rather than the disc's executable. That includes Super Robot Taisen Operation Extend from a real NPUMDIMG EBOOT.PBP, which settles that ISO.BIN.EDAT does not re-key the PBOOT - a digital title's patched EBOOT is encrypted exactly like a UMD one. On the UMD side, the patched LittleBigPlanet reads PATCH.ARC out of the install alongside the disc's own archive. The DISC_VERSION warning turns out to be load-bearing: many of the pairs mismatch, because the dumps in circulation are later disc revisions than the updates were built against. docs/pkg_notes.md has the numbers, and the one thing that doesn't work - PGD-wrapped .sprx modules, which sceKernelLoadModuleNpDrm can't load.
