Sony's version.xml only lists the newest patch. When that one needs a
newer firmware, PatchDL now asks Prospero Patches for the version history
and offers the newest patch that still runs on the console. Prospero only
hands out download links after a human check, so a guide with a QR code
moves the user to a phone, where they copy the SC link. PatchDL derives
Sony's manifest from that link and downloads like an official update.
The game list now groups by what the user can do: Updates, Up to date,
Not supported. Update all read a nonexistent state.games and did nothing;
it now uses state.titles.
