Chasing why (A) does not advance the title turned up four harness bugs, one real
root cause, and a refutation of that root cause as the explanation.
FIXED, each verified:
* boot_menu.sh sent the emulator stdout to /dev/null, which is why none of the
rest was visible. It now keeps a log and prints its path.
* skip_intro.sh probed pixel (625,618) for the green (A) glyph - a 1280x720
coordinate. screenshot returns the 1279x675 game surface, where that point
is on the copyright line and reads (8,17,31). Symptom: a 600s TIMEOUT with
the title on screen. Now classified with screen_id.py; next boot printed
"TITLE at 239s -> A".
* skip_intro.sh no longer taps through the movies. Making that press real (the
vgamepad fix) was a REGRESSION: the boot then reached the title in 90s and
that title accepted nothing. menu_draw_capture.sh records the same finding
independently.
* boot_menu.sh signs in whichever profile exists instead of a hard-coded XUID.
ROOT CAUSE FOUND: naming a XUID with no profile behind it opens a sign-in
dialog, xam_dialogs_shown_ goes to 1, and IsUIActive() then discards every
XamInputGetKeystrokeEx. Measured 8,388,601 swallowed calls in one boot with the
pad log showing presses arriving normally throughout. Only B13EBABEBABEBABE
exists on disc; the script asked for E0300000EFBEA3D4. Signing in the real
profile takes the swallow count 8,388,601 -> 0.
AND REFUTED: that is not why the title is stuck. With a valid profile and zero
swallowed keystrokes, a single (A) on the title that ends the boot still does
nothing. The dialog bug was real and worth fixing; it is not the explanation.
Next probe is specific: --log_mask=13 records no kernel calls, so it is not even
known whether the game polls at the title. A log on the SUCCESSFUL
XamInputGetKeystrokeEx return, mirroring the one already on the swallow path,
answers it in one boot.
