The disc-updater install ran when ltn0.pgf was missing, so a font set unpacked
from an old UMD looked complete forever, and a later game wanting a font its own
firmware added silently got a bundled substitute instead.
Requiring the whole registry doesn't work either: firmwares older than a font
can never satisfy it, so we'd unpack the same updater on every launch and
announce it each time. What settles it is that a game can't ask for a font that
didn't exist when it was made. Record the earliest firmware known to ship each
font in the registry, and only require the ones the running game's firmware
would have had.
The version comes from PARAM.SFO's PSP_SYSTEM_VER, with the bundled updater's
version as a fallback. That keeps the whole thing stateless - nothing recorded
that could go stale when flash0 or the ini gets moved around.
Survey of a large library, unpacking flash0:/font from each disc's updater
across firmware 1.50 to 6.60: jpn0 and ltn0..ltn15 are in every one of them, and
kr0.pgf is the only registry font that arrived later - absent in 1.50, present
from 1.52.
Uses one directory listing rather than a stat per font, since on Android's
scoped storage the individual checks are slow.
sceFont never looked at flash0:, so a firmware the user installed was
ignored and we always fell back to our bundled substitutes - despite
the "ignoring NAND" warning suggesting otherwise. It reads flash0:/font
now, after the game's own fonts and the classic ms0 override.
And if there's nothing in NAND, we unpack just flash0:/font out of the
firmware updater on the running disc, which most UMDs carry. That turns
"install a firmware first" into something that happens by itself for
anyone playing a retail game.
EmulatedModelGeneration moves from InstallUpdateScreen into PSARUnpack
so both callers pick the same firmware file list.
