Intro (publisher logo and opening text)

What is shown

From a fresh save with Cross pressed every 15 s, it shows the Good Shepherd Entertainment logo at 30 s, then the opening line "This is not the story of the One; the One encompasses too much, crushing everything and making it the same." The window title reports 7.0, 5.1, 1.5 and 1.7 FPS at 30, 48, 66 and 84 s. It then stops in the AGC driver at 90.4 s:

[videoout] presentation failed: AGC graphics: vertex fetch exceeds descriptor record count

With #9604's more detailed message, the same run stops at 88.5 s on:

vertex fetch exceeds descriptor record count: OOB_SELECT 2, stride 12, NUM_RECORDS 303, vertex index 319706

RDNA 2 doesn't check the record count of a strided fetch with OOB_SELECT 2, and the hardware returns the stored values past NUM_RECORDS. That was measured with tools/hw-oracle in #2241 (comment). AnyPS5 still throws for that case, as recorded in docs/dev/debt/libSceAgcDriver.md. More on #9604: #9604 (comment)

Current blocker

Strided vertex fetch with OOB_SELECT 2 past NUM_RECORDS throws instead of reading the stored bytes.

How it was run

relinker --registry --rpath <build>/core/libs/libs eboot.elf app.elf

Modules in sce_module are converted with the title. This dump has no PlayGo files, so it was run with APS5_PLAYGO_UNLISTED_CHUNKS=installed.

AI-assisted testing and report: yes, Claude Code.

With #9915 (strided vertex fetches with OOB_SELECT 2 and 3, by ebarr24) merged on main fe8b9b5ddd, the stop at 88 to 90 s is gone: no driver stop in 300 s. It shows "Part I — What an unfortunate place for a beginning…" over the first 3D scene at 240 s, and the scene with the HUD at 295 s. From about 130 s it runs at 0.2 to 0.26 FPS, and the scene is very dark with saturated yellow areas whose correctness I have not checked. No gameplay input was tried. Details: #9915 (comment)

AI-assisted: yes (Claude Code).
