Q2. The archive is eight screens shipped twice, English and Japanese -- not the "build 4 title, 5 main menu, 6/8/9 submenus" the handoff claimed. Build 8 is the JAPANESE main menu; 6 and 9 are the EN and JP EXTRAS, and EXTRAS is the only submenu GP_TITLE holds. The PRESS (A) BUTTON plate is its own build (2/3), composited over the title art and faded in a beat later, not a state of build 4. Confirmed by booting to the main menu and walking it: title, PRESS (A), main menu and EXTRAS each match their render element for element. Builds 0/1 and 10/11 -- a DELTASABER / SYLPHEED A.I. plate -- were looked for in the whole boot filmstrip, every title-side screen and the attract loop, and appear in none of them; the reach of that negative is written down rather than filled in with a guess. Two rig traps went into METHOD: the menus drop d-pad presses shorter than ~0.3 s, and a grab 2.5 s after a transition can catch a screen mid-fade -- which nearly wrote "the returned title has no plate" into the corpus.

Which GP_TITLE build is which screen — measured against the running game
Status: ✅ CONFIRMED for the four screens the boot path actually shows
(title art, PRESS Ⓐ BUTTON, main menu, EXTRAS); 🟡 PROBABLE for their
Japanese twins; ❔ open for the two DELTASABER plates.
Answers MISSION Q2. The previous statement — "build 4
title, 5 main menu, 6/8/9 submenus" — is partly wrong and is withdrawn:
build 8 is the Japanese main menu, not a submenu, and GP_TITLE holds
exactly one submenu (EXTRAS), in two languages.
The archive is eight screens, each shipped twice
GP_TITLE.pak has 16 entries; sylpheed-cli screen list calls 12 of them
composable builds. The 16 fall into eight pairs, and each pair's two members
have near-identical sizes and name hashes that differ by a constant — one
character of the name apart:

For the three pairs whose members differ visibly — C, D, E — the difference is
English versus Japanese: build 7 is the title art with the katakana subtitle
プロジェクト シルフィード, build 8 the main menu reading 新規 / ロード /
チュートリアル / オプション / エクストラ, build 9 the EXTRAS submenu as
エクストラ. That is the whole of the language split we can see. In pairs A, B and
H the two members render byte-identical PNGs — the archive still carries two
copies, but the artwork does not change with the language.
Pairs F and G are the four entries screen list does not classify as builds.
They are not identified here.

Reach of the two negatives. Builds 0/1 and 10/11 were looked for in: the whole
boot sequence (a 5 s-cadence filmstrip from launch to the title, ~190 s), the
title, the main menu, the EXTRAS submenu, the LOAD GAME slot list, the
transition into MISSION SELECT (a 40-frame burst), and the attract cycle. They
appear in none of them. The obvious remaining candidate is a long load — a
mission launch — which is out of this objective's scope; they are most likely a
loading/AI-chatter plate. That is a hypothesis, not a result.
Three things the captures settle beyond the map
The live title is two builds composited. Build 4 draws the art; build 2 draws
PRESS Ⓐ BUTTON on top, and it fades in a beat later — a screenshot taken
2.5 s after arriving at the title has the art and no plate, one taken ~1 s later
has both. The port must treat the plate as its own timed element.
The attract-loop title carries the plate too. After ~8–10 s idle the title
fades to black, a full-motion video plays for ~85 s, and the title comes back —
with PRESS Ⓐ BUTTON
(live-attract-title-press-a-band.png).
This is consistent with, and adds nothing to, the draw-quad comparison in
canary-scripted-input-traps.md: the plate is
not the tell that distinguishes the boot title from the attract title.
EXTRAS is the only main-menu destination inside GP_TITLE. Ⓐ on EXTRAS
opens build 6 — measured. The other four destinations leave the archive: Ⓐ on
LOAD GAME opened a LOAD GAME slot list, and Ⓐ on MISSION SELECT inside
EXTRAS opened a MISSION SELECT screen, neither of which is a GP_TITLE
build. dat/ carries GP_SAVE_LOAD.pak, GP_TUTORIAL.pak, GP_OPTIONS.pak,
GP_MISSION_SELECT.pak and GP_MOVIE_THEATER.pak; that those are the archives
behind the other four buttons is an inference from the names, not a measurement.
