re: the movie/subtitle/voice link is solved statically -- INDEX called it a dynamic unknown

Browse Source 
INDEX carried IXUD as "movie<->track link unknown (dynamic item)". It is a
config record on the disc: tables.pak schema 0x067025b9, whose keys match the
movie game-part symbols in the executable (MOVIE / TELOP / SUBTITLE /
VOICETRACK, plus SUBTITLE_FONT / SUBTITLE_Y / SUBTITLE_HEIGHT next to
silph::GamePart_Movie::Impl::OnPrepare).

101 movies mapped: 94 with a subtitle, 83 with a voice track, 21 with a telop.
Every subtitle reference was looked up in dat/movie/<lang>.pak and 93 of 94
resolve -- SUBTITLE_S12B.tbl resolves in NONE of the six languages, a dangling
reference on the retail disc rather than a decode failure.

Naming is SUBTITLE_<base>.tbl and VOICE_<base>, with the staff roll and five
supply movies (VOICE_D_450..454) as documented exceptions, so a reimplementation
can resolve by convention and fall back to the table for those six.

Deliberately NOT published: the record's ~104 script ids paired to movies.
Positional pairing drifts by three -- visible at the tail, where
S24/S27_SUPPLY_ACROPOLIS would have to map to hokyu_LS_s24A/s27A and do not --
because the IDXD pool dedupes repeated values and an id whose movie was already
named contributes no token. The CSV is keyed by movie file instead.

For the intro-movie work: ADV.wmv has VOICE_ADV and no subtitle, no telop.
