roster_target had flagged a contradiction: S10, a STORY stage, still fielded an
unharvested unit, which the "story campaign complete at 68 units" claim did not
account for. S10 was simply never flown. Flying it settles it:
UN_e005_ADAN_ElanTypeQ_Margras is in the snapshot, 144 rows, and the merge takes
the file 68 -> 69 units, 9 393 -> 9 537 rows, 7 115 -> 7 204 defaulted-on-disc
values, with 154 disc cross-checks agreeing and 0 disagreeing. roster_target now
reports S10: 0 missing, and every remaining gap is a CHALLENGE stage
(S24/S25/S27/S28/S29).
A much simpler way to fly a story stage, replacing the save-editing route
(tools/re-capture/fly_stage.sh): poke ONE word -- 0x828F40C0 = 0x0001FFFE marks
stages 1-16 cleared -- and MISSION SELECT will launch any of them. Nothing is
written to disc, so there is no save to back up and restore, and TRAP 1 from the
old recipe (launch_mission.sh silently loading the last-used slot) cannot happen.
Route, learned by screenshotting each step: MISSION SELECT -> pick stage -> A ->
mission briefing (A: Continue) -> READY ROOM -> TAKE OFF -> flight. The READY
ROOM carries an "EXTRA" watermark, which is the static analysis's mission-KIND
= 3 ("EXTRA" config section, docs/re/challenge-mission-gate.md section 4) visible
on screen -- an independent confirmation of that field's meaning.
Also recorded: a snapshot taken at the BRIEFING yields 0 runtime objects. Unit
definitions are instantiated at stage load proper, so the snapshot has to wait
for flight; the briefing screen is too early.
Runtime-capture harness (sylph-re container)
Screenshot-driven scripts for reading the running retail game's menus under Xenia
Canary + lavapipe, headless. They assume the container helpers screenshot,
vgamepad, pad are on $PATH and HOME=/sylph-home/re.
| Script | What it does |
|---|---|
skip_intro.sh |
Boot → main menu, unattended. Taps A only while the intro movie is actually playing (frame-to-frame RMSE), then once at the PRESS Ⓐ BUTTON title. Static logo screens are left alone, so a stray tap can never land on NEW GAME. |
wait_title.sh |
Older variant: wait for the title (green Ⓐ glyph at px 625,618) and tap A. Superseded by skip_intro.sh. |
step.sh |
One Arsenal navigation step (down/up/next/prev/none) + a compact capture: weapon list stacked over the DATA SHEET. |
sweep.sh |
Walk a whole weapon-type list, capturing only rows that show a DATA SHEET — locked rows (a "Conditions to Develop" panel) are detected by the brightness of the Range Class label box and skipped. |
type.sh |
Change weapon-type tab N times (RB) and report the header strip. |
hp.sh / cyc.sh |
Hangar hard-point carousel: cyc.sh steps it (d-pad down, not left/right) and captures the Name + DATA SHEET. |
Input timing under lavapipe: the game polls input at its own low frame rate, so a 60 ms d-pad tap is dropped roughly half the time. 200 ms is reliable; 300 ms starts to auto-repeat (two rows per press).
Findings produced with these: docs/re/weapon-datasheet-runtime.md.
Guest-memory tools (no screenshots)
| Script | What it does |
|---|---|
gmem.py |
Read the live guest address space out of /dev/shm/xenia_memory_* (Xenia's backing file), addressed by guest VA. find / read / words. |
weapon_runtime.py |
Solve the Weapon/Shell struct layouts against the disc records and read the fields the disc defaults. |
unit_discover.py |
Find which runtime class carries a set of ID strings, assuming no vtable: tallies the word at pointer_site - k across distinct IDs. |
unit_runtime.py |
Same solver for the unit\UN_*.tbl definition objects (vtable 0x820af844). Unions several snapshots — unit definitions are per-stage. |
schema_order.py |
Merge a sub-record's field-declaration order across all tables (topological sort); the layout check that pins fields no table ever values. |
order_check.py |
Test offset = base + 4*index for one table's sub-record against solver output. |
grab_tutorial.sh |
Cold-boot Canary, walk to the Nth TUTORIAL entry, wait for the stage load, snapshot guest RAM. One emulator per capture — backing out of a loaded mission wedges it. |
Snapshot first — cp --sparse=always /dev/shm/xenia_memory_* snap.bin (~2 s) — and
point $GMEM_FILE at the copy; the running emulator pegs every core under lavapipe.
