re: what the game actually reads at boot -- config.ini, and which
GameParts exist at all Q6's second half, advanced but not closed, and the negative is the point. config.ini is the disc's ONLY config file -- one find over the whole extract -- and its own Shift-JIS header calls it the "Application / GamePart initial settings table". Its [SYSTEM] section, which that same comment says holds what the game and every game part share, is EMPTY. So the boot order is not in disc-side configuration at all, and that search space is now closed rather than merely unexplored. What the file DOES carry is the language: XC_LANGUAGE_* -> eng/jpn/deu/ fra/esp/ita, defaulting to eng. That is the mechanism behind the EN/JP build pairs in GP_TITLE and the <lang>.pak families -- a question the corpus had described but never traced to its input. Then the registry. Pulling every RegisterToFactory diagnostic string binds 24 of the 29 GamePart ids to a C++ class, and five ids have no registration site: 1, 2, 16, 18, 28. Id 1 is GP_ADVERTISE_DEMO, which agrees with what I measured two iterations ago -- the attract loop is the TITLE replaying ADV.wmv, not a transition into an advertise part. Marked amber, not green: it is an argument from an error message, not from code. Two things fall out for Q4: ids 3 and 4 are the same class (GamePart_SaveLoad, one part with two ids), and the menu buttons' ids now match the executable's own class names rather than a list of table names. Still a name match, one level closer to the code. What is still missing is the transitions themselves, and I say so: the manifest gives the boot-side assets, config.ini the language, the registry which parts exist. What decides to advance is in GamePart_Title's code and that dig has not been started.

# What the game reads at boot — `config.ini`, and which GameParts actually exist
|
||||
|
||||
**Status:** ✅ `CONFIRMED` and **decoded** for the language selection. ❔ a bounded
|
||||
**negative** for the boot *order*. 🟡 for what the registration strings imply
|
||||
about the attract loop.
|
||||
|
||||
Contributes to [MISSION Q6](../port/MISSION.md), and firms up Q4's ids.
|
||||
|
||||
## ✅ `config.ini` — the disc's only config, and it selects the language
|
||||
|
||||
`config.ini` sits at the **disc root**, is 400 bytes, and is the **only** `.ini`,
|
||||
`.cfg` or `.txt` anywhere on the disc. Its own header comment (Shift-JIS) names
|
||||
it:
|
||||
|
||||
> `アプリケーション/ゲームパート初期設定テーブル`
|
||||
> — *"Application / GamePart initial settings table"*
|
||||
>
|
||||
> `SYSTEM セクションには、ゲーム及び各ゲームパートで共通にアクセスする情報を記述する`
|
||||
> — *"the SYSTEM section describes information accessed in common by the game and
|
||||
> each game part"*
|
||||
|
||||
```ini
|
||||
[SYSTEM]
|
||||
|
||||
[LANGUAGE]
|
||||
= eng ; default
|
||||
#0x01 = eng ; XC_LANGUAGE_ENGLISH
|
||||
#0x02 = jpn ; XC_LANGUAGE_JAPANESE
|
||||
#0x03 = deu ; XC_LANGUAGE_GERMAN
|
||||
#0x04 = fra ; XC_LANGUAGE_FRENCH
|
||||
#0x05 = esp ; XC_LANGUAGE_SPANISH
|
||||
#0x06 = ita ; XC_LANGUAGE_ITALIAN
|
||||
```
|
||||
|
||||
**This is the mechanism behind the EN/JP screen pairs.** The console's
|
||||
`XC_LANGUAGE_*` setting selects a three-letter code, and that code is what picks
|
||||
`GP_TITLE`'s English or Japanese build ([`ui-title-build-map.md`](ui-title-build-map.md))
|
||||
and the `<lang>.pak` families. Default is `eng`, keyed by the empty line — an
|
||||
unlisted language falls back to English. ✅ decoded. The executable does read the
|
||||
file: the string `config.ini` is at `.rdata 0x82062b44`.
|
||||
|
||||
## ❔ But the boot ORDER is not in it — and this is the whole search space
|
||||
|
||||
`[SYSTEM]` — the section the file's own comment says holds what the game and every
|
||||
game part share — is **empty**. So the file the game itself calls the *GamePart
|
||||
initial settings table* says nothing about which part runs first or what follows
|
||||
what.
|
||||
|
||||
**Reach of the negative:** this is the only config file on the disc (one `find`
|
||||
over the whole extract). The boot order is therefore not in disc-side
|
||||
configuration at all; it is in code, or in a table inside the executable that has
|
||||
not been located.
|
||||
|
||||
## 🟡 `GP_ADVERTISE_DEMO` is never registered — the attract loop is not its own part
|
||||
|
||||
The executable carries one diagnostic string per GamePart registration site
|
||||
(`silph::GamePartTask::RegisterToFactory<N, class silph::GamePart_X>::RegisterToFactory is failed!`)
|
||||
— the same evidence the corpus used to pin the id table
|
||||
([`challenge-mission-gate.md`](challenge-mission-gate.md) §3). Extracting all of
|
||||
them gives **24 of the 29 ids bound to a C++ class**; full list in
|
||||
[`data/gamepart-class-ids.txt`](data/gamepart-class-ids.txt).
|
||||
|
||||
**The five ids with no registration site are `1`, `2`, `16`, `18`, `28`** — in the
|
||||
id table's naming, `GP_ADVERTISE_DEMO`, `GP_SELECT_STORAGE`, `GP_DEMO`,
|
||||
`GP_SELECTOR`, `GP_TEST`.
|
||||
|
||||
That `GP_ADVERTISE_DEMO` (1) is among them matters for Q6, and it agrees with
|
||||
what was measured: the attract loop is **the title screen replaying `ADV.wmv`**
|
||||
([`movie-binding.md`](movie-binding.md)), not a transition into a separate
|
||||
advertise part. The id table names a part the shipped build never registers.
|
||||
|
||||
🟡 **not ✅**, because this is an argument from a *diagnostic string*: no error
|
||||
message for id 1 implies no registration site for id 1. That is how the corpus
|
||||
already reads these strings, and it is sound, but it is not the code.
|
||||
|
||||
### Two bonuses for Q4
|
||||
|
||||
* **`3` and `4` are the same class** — `GamePart_SaveLoad` is registered twice.
|
||||
The id table's separate `GP_LOAD` / `GP_SAVE` names are two ids on one part.
|
||||
* The ids behind the menu buttons now match the executable's own **class** names,
|
||||
not just a list of table names: `GamePart_Options` = 8, `GamePart_Tutorial` =
|
||||
25, `GamePart_Extras` = 5, `GamePart_MissionSelect` = 7,
|
||||
`GamePart_MovieTheater` = 6, `GamePart_Title` = 0. Still a **name match** —
|
||||
screen title ↔ class name — but anchored one level closer to the code.
|
||||
|
||||
## What is still missing for Q6
|
||||
|
||||
The *transitions*. Nothing found so far says "title, then movie, then title" — the
|
||||
manifest gives the boot-side **assets** in play order
|
||||
([`movie-binding.md`](movie-binding.md)), `config.ini` gives the **language**, and
|
||||
the registry gives **which parts exist**. What decides to advance is in
|
||||
`GamePart_Title`'s own code, and reading it is a static PPC job that has not been
|
||||
started.
