Every FILES path hashes straight into the sound.pak TOC (5135/5135, path as stored). The archive is then almost fully accounted for: 5100 jpn + 4382 eng + 35 BGM/JNGL = 9517 of 9519. Only eng and jpn resolve -- deu/fra/ita/esp give zero, which is the archive-side measurement behind 'two voice sets shipped'. 718 Japanese banks have no English counterpart. More importantly this bounds an existing result. The leading-region rule from voice-bank-leading-region.md reproduces its five documented banks EXACTLY under eng\etc\ (16384/2048/14336/45056/59392), so the pipeline is sound -- but it holds for only 1571 of 4382 English banks and for ZERO of 5100 Japanese ones. It is a property of some English banks, not of .slb in general, and the Japanese layout is undecoded. I nearly misread this as a broken extractor, because FILES lists jpn paths and those gave non-multiples of 2048. Reproducing the recorded figures exactly under eng is what distinguished a wrong assumption from a wrong reader.

What is actually in sound.pak — and the language substitution
✅ Settled 2026-08-26. sound.pak's 9 519 entries are almost entirely
accounted for: the Japanese voice set, the English voice set, and 35 music /
jingle banks. The FILES record in tables.pak names the Japanese half, and
the game reaches the English half by substituting the leading directory.
Until now the corpus described sound.pak as "~9 519 headerless entries, params
in an unknown table". The table is
sound-cue-table.md, and this page is the census.
The name is the key
Every path in FILES hashes straight into the sound.pak TOC with
name_hash — 5 135 of 5 135, using the path exactly as stored
(backslashes, case-insensitive):
jpn\etc\VOICE_D_257.slb -> name_hash -> TOC entry (offset, size)
No transformation, no prefix, no stem. Taking the basename instead resolves only
35 — precisely the 35 root-level BGM_* / JNGL_* banks whose basename is
their path, which is the control that shows the full path is what matters.
This is not luck: the hash's low 24 bits are a residue mod 0x00FFF9D7 and the
top byte is a byte-sum, so for 5 135 probes against 9 519 occupied slots the
expected number of accidental hits is about 0.01.
The census
| what | entries |
|---|---|
jpn\… — named directly by FILES |
5 100 |
eng\… — the same names with the directory substituted |
4 382 |
BGM_*.slb, JNGL_*.slb at the root |
35 |
| total accounted | 9 517 |
| TOC total | 9 519 |
2 entries are unaccounted for. I did not identify them.
Only eng and jpn resolve. deu, fra, ita, esp and the alternative
spellings fre/ger/spa produce zero hits, which is the measurement
behind the claim that only two voice sets are shipped — the other four languages
are subtitle-only.
718 of the 5 100 Japanese banks have no English counterpart. That is consistent with the previously recorded finding that a set of lines exists only undubbed, and it puts a number on it from the archive side.
⚠️ The leading-region rule is English-only
This is the part that matters most, and it bounds an existing result.
voice-bank-leading-region.md established
the hybrid layout: a bank may carry a leading headerless XMA1 region before its
first RIFF, recognised by the first RIFF sitting exactly at
1392 + n·2048. That was derived from VOICE_D_450–454, and it reproduces
exactly — all five, at 16 384 / 2 048 / 14 336 / 45 056 / 59 392 bytes,
matching the recorded figures to the byte. The pipeline is sound.
But those five are eng\etc\ banks, and the rule does not generalise:
| set | aligned | misaligned | no RIFF |
first RIFF ≤ 1392 |
|---|---|---|---|---|
eng\… (4 382) |
1 571 | 2 060 | 696 | 55 |
jpn\… (5 100) |
0 | 4 301 | 799 | — |
Not one of the 5 100 Japanese banks satisfies the alignment condition. The rule describes a third of the English set and none of the Japanese set.
Being careful about what that does and does not mean: "misaligned" only means
the leading-segment branch does not fire, and to_xma_riffs still walks the
bank's sub-waves normally — so this is not evidence that those banks are
broken. What it does mean is that the leading-region finding is a property of
some English banks, not of .slb in general, and any code or documentation
that treats it as the bank format is overreaching. The Japanese banks are
laid out differently and that layout is not decoded.
How I nearly got this wrong
I first resolved the five documented banks through their FILES paths, which
are jpn\etc\…, and got leading regions of 59 600 / — / 6 352 / 14 544 /
28 880 — none a multiple of 2 048, none matching the recorded figures. The
tempting reading was that my extraction was broken. The alignment condition is
what said otherwise: a broken reader would not produce exactly the recorded
numbers for eng\etc\, which it then did, for all five. The extraction was
right and the assumption that FILES' path was the one the corpus had measured
was wrong.
What this does not settle
- The 2 unaccounted TOC entries.
- The Japanese bank layout. 4 301 banks have a
RIFFat an unaligned offset and 799 have none at all; neither shape has been decoded, and no Japanese bank has been decoded to audio here. - Why 55 English banks have their first
RIFFat or before 1392, inside what the headerless reading treats as the header. - Nothing here was run. This is a static census of the archive.
