Two routes closed, both cheaply. The loading screen was the best discriminator reachable WITHOUT navigation — its full-screen element is declared 7th of 10, so the two candidate orders would look completely different. It does not appear during the boot at all: 23 captures armed across an entire boot are all intro-movie frames, two full-screen quads apiece. It belongs to a content load, which is behind the main menu, which is behind the (A) that works half the time. And a loophole this document had left open is shut: the title's sprites were matched to build 4 BY SIZE, so the game might have been running some other build whose table lists them in the captured order. Only two bundles in GP_TITLE.pak contain all seven sprites, and neither is ascending in the captured order. Recorded rather than glossed: one sub-order is genuinely ambiguous, because ptlogo_back2eff and ptlogo_back2eff5 decode to the same 1133x280 and sit at declaration 20 and 18, either side of ptlogo_back2 at 19. The UI quad carries a k_8_8_8_8 colour attribute the hook does not log yet, and the two rest at different fade alphas — logging it would name them apart.

# Capture the LOADING screen's draw order. No navigation and no pad input at all:
|
|
# the loading screen appears on its own during the boot, which matters because
|
|
# (A) at the title only works about half the time.
|
|
#
|
|
# Why this screen: GP_TITLE's 10-element loading build declares its FULL-SCREEN
|
|
# element (`pgloading_baseeff`, 640x360 at 200%) SEVENTH of ten, behind the
|
|
# spinner and the "NOW LOADING" text. So it can tell "declaration order" apart
|
|
# from "background first" — which the main menu could not, because its
|
|
# background sits at index 1.
|
|
#
|
|
# F10 arms the capture (unconditionally, since 2026-08-19) and also opens the
|
|
# emulator's menu bar, so each press is followed by a click on the game surface.
