# The movie ↔ subtitle ↔ voice link ✅ (static)

[`INDEX`](INDEX.md) carried the IXUD subtitle format as 🟡 with **"movie↔track
link unknown (dynamic item)"** — i.e. a question expected to need the running
game. It does not: the link is a config record on the disc, and it verifies
against the disc's own contents.

## Where it is

`dat/tables.pak`, the IDXD record with schema `0x067025b9`. Its keys come from
the movie game-part — the executable carries them next to the symbol
`silph::GamePart_Movie::Impl::OnPrepare`:

```
PATH = dat\movie\      SUBTITLE_FONT = fra.pak+GOTHICB.TTF
SUBTITLE_Y = 600       SUBTITLE_HEIGHT = 33
MOVIE   TELOP   SUBTITLE   VOICETRACK
```

Each movie is one group of values:

```
S02A.wmv                              MOVIE
fra.pak+pwterop_s02a.prt              TELOP        (optional overlay)
fra.pak+SUBTITLE_S02A.tbl             SUBTITLE
VOICE_S02A                            VOICETRACK
```

`<lang>.pak+<member>` resolves inside `dat/movie/<lang>.pak`, and the six
language paks (`eng`, `fra`, `deu`, `esp`, `ita`, `jpn`) each carry the same
member names — so the prefix in the table is just the build's language and the
member name is the portable part. The recovered map is
[`captures/movie-subtitle-voice-map.csv`](captures/movie-subtitle-voice-map.csv):
**101 movies, 94 with a subtitle, 83 with a voice track, 21 with a telop.**

## Verified, and one real defect

Every subtitle reference was looked up in the language paks. **93 of 94 resolve.
`SUBTITLE_S12B.tbl` resolves in none of the six languages** — a dangling
reference on the retail disc, not a decode failure on our side. Worth knowing
before the reimplementation treats a missing subtitle table as a bug of its own.

The naming is a convention with two documented exceptions:

- subtitles are `SUBTITLE_<movie base>.tbl` — the only departure is the staff
  roll, `SYLPH_HD720p_8M-CBR_2ch.wmv` → `SYLPH_HD720p_8M-CBR_2ch.tbl`;
- voice tracks are `VOICE_<movie base>` — except five supply-run movies
  (`hokyu_LS_s02A`, `hokyu_LS_s02H`, `hokyu_DS_s02A`, `hokyu_DS_s07H`,
  `hokyu_LS_s09A`), which point at shared lines `VOICE_D_450…454`.

So a reimplementation can resolve a movie's subtitle and voice **by convention**,
and should fall back to this table for those six cases rather than assuming it.

## What is *not* recoverable from this record

The record also lists ~104 **script ids** (`LOGO1`, `ADVERTISE_MOVIE`,
`STAFF_ROLL`, `MS00A`, `STAGE01_PHASE01`, `S02_SUPPLY_ACROPOLIS`, …) — the names
stage scripts use to trigger a movie. Pairing them positionally with the 101
movie groups **does not work**: the counts differ by three and the drift is
visible at the tail, where the last ids (`S24_SUPPLY_ACROPOLIS`,
`S27_SUPPLY_ACROPOLIS`) would have to map to `hokyu_LS_s24A.wmv` /
`hokyu_LS_s27A.wmv` and under positional pairing do not.

The cause is the same IDXD property that bit the Arsenal table: **the string pool
stores each distinct string once**, so an id whose movie was already named
earlier contributes no new value token and its group silently disappears. The id
list is therefore ❔ until the binary node/index region is decoded — and the CSV
is deliberately keyed by **movie file**, which is the part the data actually
supports.

## Note for the intro-movie investigation

`ADV.wmv` — the one the emulator work is about — has `VOICETRACK = VOICE_ADV`
and **no subtitle and no telop**. So a correct playback of it needs the video and
that one voice track, nothing else from this table.
