sylpheed-port's BLOCKED.md ask #1 -- does (B) from EXTRAS also show no black interval, or is "(B) has no black" one screen pair -- needs the harness to know it is on EXTRAS. screen_id.py cannot tell: both are dark blue GP_TITLE screens and it reports `menu` for either. which_title_screen.py correlates a grab against our build 5 / build 6 renders. First version FAILED its control: it called live-main-menu.png "extras" and live-extras.png "main_menu", both backwards, margins under 1.1 on RMSE ~33. Cause: it applied the y=45 game-surface offset unconditionally, but only a full 1280x720 display frame has the menu bar -- a 1279x675 grab IS the surface, and two of the three reference captures are surface-sized. Offset made conditional; the control now passes 4/4 with margins 9.9-11.7 against ~18 within-class. The tool is a navigation aid for driving the emulator and says so: it identifies a screen by agreeing with our own renders, so nothing measured may rest on it. Also records the METHOD entry sylpheed-port offered from their own wedged check script: an absence of output is not a status. They reported "still running, two lines, both ok" for three iterations while the first attempt had died silently under its own timeout with block-buffered output -- zero information, reported as patience. An orphan from an older form of the same script was found running after 9.5 hours. Line-buffer and bound long jobs, and check the artifact rather than the exit code: the artifact reached its correct duration while the process never returned.

# Decompose a screen transition's ~0.4 s fade-out into RAMP + HOLD, at the
|
|
# emulator's own frame granularity.
|
|
#
|
|
# docs/re/screen-transitions.md measures the fade-out as ~0.4 s (~24 units) while
|
|
# `pteff00.prm`'s final declared ramp is 70->80 = 10 units. The remainder is
|
|
# currently ARITHMETIC THAT FITS -- "the other 14 units must be the black hold"
|
|
# -- and that page says so itself. This measures it instead.
|
|
#
|
|
# The design point: arm the UI draw capture ON THE MAIN MENU, then press (B).
|
|
# One capture window then contains
|
|
# * the menu's fade-OUT -- the unknown, and
|
|
# * the title's fade-IN -- whose ramp IS decoded from the file (build 4's
|
|
# pteff00.prm, t=16 a=255 -> t=261 a=0, 245 units),
|
|
# so the run carries its own control: an instrument that cannot reproduce the
|
|
# known fade-in cannot be trusted on the unknown fade-out.
|
|
#
|
|
# Traps inherited from menu_draw_capture.sh, both already paid for:
|
|
# * F10 arms the capture AND opens the emulator menu bar; any Xenia UI makes
|
|
# IsUIActive() true and every later guest keystroke is swallowed. Click the
|
|
# game surface to dismiss before touching the pad.
|
|
# * a 0.12 s tap gets missed; hold (B) 0.5 s and confirm [RE-INPUT] delivery.
|
|
#
|
|
# WHERE=menu (default) arms on the main menu and presses (B) -> menu -> title.
|
|
# WHERE=title arms on the boot title and presses (A) -> title -> menu.
|
|
# WHERE=extras navigates to EXTRAS, arms there, presses (B) -> menu.
|
|
# Tests whether "(B) has no black interval" is a rule or
|
|
# one screen pair -- sylpheed-port's BLOCKED.md ask #1.
|
|
# The two transitions have DIFFERENT declared fade-ins for the incoming screen --
|
|
# build 4 is 0->16 (16 units, 8 frames), build 5 is 0->12 (12 units, 6 frames) --
|
|
# which is what makes the pair a discriminator rather than a fit.
|
|
#
|
|
# Usage: WHERE=title fade_decompose.sh [out_dir]
