re(challenge): the unlock is a bit test, and the mission table is on disc
Static only. Bounding each GamePart's code block by its factory creator thunk (id -> creator recovered for 22 of 24 registrations at 0x8280C000-0x8280F800) puts GamePart_ChallengeMission at 0x82187E60-0x8218CF10. Resolving every string that block references gives the screen's config schema, and the record itself is on disc -- tables.pak schema 54a10697, one copy per language, English entry #64. Six missions: TimeAttack (record Time), ScoreAttack (record Points) and Extra01..Extra04, each with MISSION_ID / REQUIREMENT / REQUIREMENT_DESC / THUMBNAIL / STAGE_DESC / NEW_STAGE and a NORMAL_BUTTON / GRAY_BUTTON pair -- so the screen always lists all six and greys out what is not earned. THE GATE (0x82189970-0x821899D8), read off the code: REQUIREMENT absent -> available REQUIREMENT == "Always" -> available else n = atoi(REQUIREMENT) n == 0 -> locked n < 24 -> test bit n of the word at singleton+80 n >= 24 -> test bit (n-24) of the word at singleton+1956 The singleton is 0x821707C0 (lazy, global 0x828F48BC). So availability is one bit in a progress bitfield and REQUIREMENT is a bit INDEX -- not a stage number, score or difficulty. Values per mission are 🟡: the pool's numeric tokens are 16/25/26/27/29 and 24/28 already appear earlier as font metrics, so they would be deduped -- which fits 24..29 but IDXD dedup makes positional pairing unsound here, so it is recorded as a hypothesis, not a table. Negative: the requirement TEXT is not in GP_CHALLENGE.pak (TextIndex over it = 0 entries; its only prose is embedded font copyright). Its PATH is a per-language branch the loader does not currently reproduce. Next: three stores to +1956 sit in 0x822C7DD0 / 0x822C8748, the same region as the save serializer 0x822C00E8 -- if the bits are save-backed, a hand-written save unlocks all six challenge missions and the last 42 units become one run.

//! RE probe: the GamePart_ChallengeMission screen config.
|
||||
//!
|
||||
//! The class's code range (`0x82187E60`..`0x8218CF10`, bounded by the factory
|
||||
//! creator thunks either side) references these config keys:
|
||||
//! MISSIONS, MISSION_ID, NEW_STAGE, REQUIREMENT, REQUIREMENT_DESC, "Always",
|
||||
//! GRAY_BUTTON, NORMAL_BUTTON, THUMBNAIL, STAGE_DESC, TEXT_STAGE,
|
||||
//! RECORD_TYPE, "Time", TEXT_RECORD, BASE_INFO
|
||||
//! i.e. the challenge list is a *config record* with a per-mission REQUIREMENT.
|
||||
//! It lives in `tables.pak` (one copy per language), not in GP_CHALLENGE.pak.
|
||||
//!
|
||||
//! Run: cargo run --release -p sylpheed-formats --example challenge_screen -- <disc-root>

range", and the kind field is the likely gate. It has never been tested — only

1–16 and 24–29 were.
|
||||
|

## 5. The unlock condition ❔
|
||||
## 5. The challenge screen, its six missions, and the unlock gate ✅
|
||||
|
||||
The factory registration sites (`0x8280C000`–`0x8280F800`) give **id → creator** for
|
||||
22 of the 24 registered parts, and the creators bound each class's code block. So
|
||||
`GamePart_ChallengeMission`'s methods are **`0x82187E60`–`0x8218CF10`** (between
|
||||
`GP_BUNK`'s creator `0x82187E38` and its own `0x8218CF10`). Resolving every string
|
||||
that range references gives the screen's whole config schema:
|
||||
|
||||
```
|
||||
MISSIONS · MISSION_ID · RECORD_TYPE · REQUIREMENT · REQUIREMENT_DESC
|
||||
NORMAL_BUTTON · GRAY_BUTTON · THUMBNAIL · STAGE_DESC · TEXT_STAGE
|
||||
TEXT_RECORD · NEW_STAGE · "Always" · "Time" · BASE_INFO
|
||||
```
|
||||
|
||||
**The record itself is on disc**, in `tables.pak` (schema `54a10697`, one copy per
|
||||
language — English is entry #64), *not* in `GP_CHALLENGE.pak`. It names six missions:
|
||||
|
||||
| slot | `MISSION_ID` | buttons / thumbnail | record |
|
||||
|---|---|---|---|
|
||||
| 1 | `TimeAttack` | `Button_TimeAttack{,_Gray}`, `Thumbnail_TimeAttack` | `Time` |
|
||||
| 2 | `ScoreAttack` | `Button_ScoreAttack{,_Gray}` | `Points` |
|
||||
| 3–6 | `Extra01`…`Extra04` | `Button_Extra0N{,_Gray}` | — |
|
||||
|
||||
`GRAY_BUTTON` is the locked art, `NORMAL_BUTTON` the unlocked art — so the screen
|
||||
always shows all six and greys out what you have not earned. Full dump:
|
||||
[`captures/challenge-screen-config.txt`](captures/challenge-screen-config.txt).
|
||||
|
||||
### 5.1 The gate is a bit test against a progress bitfield ✅
|
||||
|
||||
`0x82189870` builds the list, and `0x82189970`–`0x821899D8` is the availability
|
||||
decision for each mission:
|
||||
|
||||
```asm
|
||||
lookup REQUIREMENT in the mission record ; bl 0x82448C50
|
||||
absent -> AVAILABLE
|
||||
== "Always" -> AVAILABLE ; strcmp, bl 0x825EDD20
|
||||
else n = atoi(v) ; bl 0x825EDCD0
|
||||
n == 0 -> LOCKED
|
||||
n < 24 -> bit n of word A
|
||||
n >= 24 -> bit (n-24) of word B
|
||||
bit set ? AVAILABLE : LOCKED
|
||||
```
|
||||
|
||||
Word A and word B are read from a **singleton** (`0x821707C0`, lazily constructed
|
||||
behind the global at `0x828F48BC`) at offsets **`+80`** and **`+1956`**. So challenge
|
||||
availability is one bit in a progress bitfield, and `REQUIREMENT` is that bit's index
|
||||
— **not** a stage number, a score, or a difficulty.
|
||||
|
||||
### 5.2 What the six requirement values are 🟡
|
||||
|
||||
The record's numeric tokens are `16`, `25`, `26`, `27`, `29`, and `24`/`28` are
|
||||
already in the pool earlier (they double as font metrics), so they would be **deduped
|
||||
away** if used. That is consistent with the six values being `24`–`29` — the same
|
||||
range as the challenge stage records — but **IDXD dedupes the string pool, so
|
||||
positional key/value pairing is not sound here** (the same trap the movie/subtitle map
|
||||
hit). Recorded as a hypothesis: reading the values properly needs the record's binary
|
||||
index section, not the pool.
|
||||
|
||||
**Negative worth keeping:** the requirement *text* (`TimeAttackRequirement`,
|
||||
`Extra01Requirement`, …) is **not** in `GP_CHALLENGE.pak` — building a `TextIndex`
|
||||
over it yields **0 entries** and its only wordy payload is embedded font copyright.
|
||||
The config's `PATH` is `dat\GP_CHALLENGE.pak+eng\`, a per-language branch, so those
|
||||
keys resolve through a naming scheme the current loader does not reproduce. Reading
|
||||
them would say in plain English what each mission asks for — worth one more attempt
|
||||
via `hash::TOC_NAME_SCHEMES`.
|
||||
|
||||
### 5.3 Why this matters operationally
|
||||
|
||||
If word A / word B are restored from the save, a **hand-written save with those bits
|
||||
set unlocks all six challenge missions** — and the savegame round-trip is already
|
||||
solved. That would turn the last 42 units of the Route-B harvest into one run instead
|
||||
of an unreachable menu. Three `stw`s to `+1956` sit in `0x822C7DD0` / `0x822C8748`,
|
||||
i.e. the same code region as the save serializer (`0x822C00E8`) and deserializer
|
||||
(`0x822C0380`) — suggestive, **not yet checked**. That is the next step.
|
||||

||||
