## ⚠️ OPEN (2026-08-26) — the Japanese voice banks are not decoded
The `sound.pak` census (see
[`structures/sound-pak-contents.md`](structures/sound-pak-contents.md)) shows
the archive is 5 100 `jpn\` banks + 4 382 `eng\` banks + 35 music banks, and
that **the leading-region rule holds for 0 of the 5 100 Japanese banks** — 4 301
have a first `RIFF` at an offset that is not `1392 + n·2048`, and 799 have no
`RIFF` at all. The rule was derived on English banks and reproduces those
exactly, so this is a limit of the finding, not a defect in the reader.
Since `FILES` names the **Japanese** set and the game substitutes the language
directory, the undecoded half is the one the table actually points at.
**First step**: take one misaligned `jpn\` bank and one `RIFF`-less one, and
locate the audio by scanning for XMA1 packet structure rather than assuming a
fixed data offset. The English aligned banks are the control — the same scan
must find their known leading region.
**Also open**: 2 of the 9 519 TOC entries are unaccounted for, and 55 English
banks have their first `RIFF` at or before offset 1392.
