Third attempt at the .tbm question. All three fixes from the previous page were applied and all three were needed: hold A for 0.5 s, confirm delivery from [RE-INPUT] rather than from the pad, and detect the screen change instead of timing it. Title at 288.6 s, both presses delivered on attempt 1, submenu at 303.4 s with 87.1 % of pixels changed. The capture is 99.7 % inked and uniform top to bottom -- a full-screen background. Our renderer gives 1.9-3.0 % for all 19 GP_SAVE_LOAD builds, 6.0-6.4 % for GP_TUTORIAL, 78.4 % for GP_SYSTEM 0/1. So two of the three archives render essentially nothing where the game draws a full screen. But WHICH screen was captured is not established, and the reason is worth more than the run: correlation cannot discriminate when the candidate renders are near-blank. All 19 GP_SAVE_LOAD builds score -0.004..-0.010 -- a ranking with no information. A matching statistic is useless against a hypothesis that predicts an empty image, which is exactly the hypothesis under test. Focus could not be read either: the two labelled menu captures fit at 2.52 and 2.48 mean absolute difference, 1.6 % apart. That is a SECOND statistic failing on the focus problem after the per-row brightness one, so it is an open item rather than an oversight. Kept regardless: the game surface sits at y=45 in the 1280x720 display frame, fitting the committed 1279x675 captures to 2.5 mean absolute difference. That is the alignment the earlier cross-geometry comparison got wrong.

Sylpheed
A clean-room reverse engineering and port project for Project Sylpheed: Arc of Deception (Xbox 360, 2007).
Three things live here, in one repository so that a change spanning them lands as one commit:
| The decoders | crates/sylpheed-formats — the disc's formats, read and verified disc-wide |
| The port | port/ — a Godot 4 project, plus crates/sylpheed-export which converts a disc into the open asset tree it reads |
| The corpus | docs/re/ — what has been reverse engineered, with its evidence, its retractions and its dead ends |
You need your own copy of the game. No game content is in this repository and none ever will be. The exporter reads the disc you supply.
The oracle is the real game
sylpheed-cliand the Explorer are tools for verifying our decoding. They are hypotheses under test and they have been wrong. When something must be checked against the truth, the truth is the game running in Xenia Canary, captured — not any renderer of ours.
This is stated first because getting it backwards is the most expensive mistake this project has made.

Xenia Canary is a separate repository: it is a fork tracking upstream, and it carries our instrumentation.
