Add a shared disc-identity module (runtime/{include,src}/disc_identity)
that opens a .cue/.bin/.iso, checks for the ISO9660 PVD (raw 2352 and
cooked 2048 layouts), reads the PVD volume id, parses the boot serial
from SYSTEM.CNF, derives the region from the serial prefix, and
optionally streams a full-file CRC32 and compares against expected
serial/CRC. This is now the single source of truth for "is this the
right disc?" — main.cpp's launch-time validate_disc_image is rewritten
to delegate to it (dropping its duplicated raw-read logic and the now
dead cue_data_path/is_iso_pvd/psx_exe_id helpers) so the launch check
and the launcher badge can never drift.
game.toml [game] gains optional disc_crc / disc_sha1 (GameConfig +
config_loader). Left unset by default: the serial check is dump-
agnostic, whereas a baked CRC would flag every legitimate dump of a
different revision/region.
Launcher: GameInfo carries the expected serial + CRC; the launcher
recomputes verification on entry and on every Browse, showing a
colour-coded badge (Serial verified / Disc verified / CRC mismatch /
Wrong game? / Not a PlayStation disc) plus a detail line with the
detected serial · region · CRC. CRC is only hashed when an expected
CRC is configured.
Verified all three tiers on Tomba: Serial verified (no CRC),
CRC mismatch (wrong CRC), Disc verified (CRC B00ECB0D match).
tools/shot_launcher.ps1: bring the launcher GL window to front and
screenshot its client area (GL windows screenshot black via PrintWindow).
