From d69272e53fd847a091bcfc5a782a09edfe2dd18f Mon Sep 17 00:00:00 2001 From: Sylpheed RE agent Date: Fri, 28 Aug 2026 18:29:39 +0000 Subject: [PATCH] re: the boot intro and the attract loop are the same video, and the new-game intro has a name Q9, answered twice over -- once from the disc and once from frames I had already captured and not used. The movie manifest's first eight slots are the whole boot-side flow, and the slot key is the role: LOGO1-4 -> logo1-4.wmv (not on the disc, which is why the splash is a screen), ADVERTISE_MOVIE -> ADV.wmv, STAFF_ROLL -> the credits reel, MS00A -> S00A.wmv, MS01A -> S01A.wmv. So the new-game intro is S00A.wmv, decoded -- which is the half I could not test at runtime, because A on NEW GAME hangs the emulator. And there is no separate boot-intro slot: ADV.wmv IS the advertise movie, the boot just plays it first. Confirmed independently by matching 19 attract frames against five candidates -- 15 hit ADV with a playhead that advances monotonically at the sampling rate and ends at 137 s, its full length, with the title back on the next sample. So the attract movie plays to its end; nothing cuts it short. That corrects me. Two iterations ago I recorded the attract movie as "~85 s, so probably not ADV.wmv" -- arithmetic on a start I never observed, since sampling began 39 s in. REFUTED and METHOD both take it, along with the matcher's real failure mode: a near-black frame has no signature, and its runner-up is not evidence. Skippability I did NOT settle, and the corpus contradicts itself: one page says A skips a movie every time, while the boot harness deliberately never taps during one because it breaks the title. Named the one-boot test rather than picking a side. --- docs/port/HANDOFF.md | 18 ++++- docs/re/INDEX.md | 1 + docs/re/METHOD.md | 9 +++ docs/re/REFUTED.md | 8 +++ docs/re/data/attract-frame-match.txt | 33 ++++++++++ docs/re/movie-binding.md | 99 ++++++++++++++++++++++++++++ tools/re-capture/frame_match.py | 21 ++++++ 7 files changed, 187 insertions(+), 2 deletions(-) create mode 100644 docs/re/data/attract-frame-match.txt create mode 100644 docs/re/movie-binding.md create mode 100644 tools/re-capture/frame_match.py diff --git a/docs/port/HANDOFF.md b/docs/port/HANDOFF.md index 077218c4..739b12da 100644 --- a/docs/port/HANDOFF.md +++ b/docs/port/HANDOFF.md @@ -32,10 +32,10 @@ authored version can be deleted. | Q3 | paint order for the six screens | βœ… answered | **decoded**: a `u16` layer key at `+0x0A` of each `T8aD` sprite header, stable-sorted with declaration index; unkeyed elements get an implied key.
