What is shown

SONIC SUPERSTARS (PPSA06888) starts on main, loads its save data (OrionOption and OrionSaveData mount), and plays its intro video; it stops at the first presentation after that. No menu yet.

Current blocker

image descriptor is incompatible with the static runtime image interface: descriptor format 7 decodes to {class 1, dim 1, ...}; modes: {class 1, dim 3, ...}; T# 025aad00 00700000 00000000 81800924 00000000 00700000 00000000 00000000

A shader takes a depth-comparison sample with dim 3D of a 1x1 1D T#. The plain sample and load forms of that access are handled by PR #____ (measured on RDNA1); the comparison sample is not measured yet. Before that, on plain main, the title stops on a SET_CONTEXT_REG_INDIRECT read inside the memory of a freed 2x multisampled target, which #4474 fixes.

Separately, moving the window while the intro plays crashed once on the CRI movie thread (null read in Unity code at app.exe+0xa7243c); not yet investigated.

How it was run

modules kept where the title has them (sce_module/ with its six bundled modules, Media/Modules, Media/Plugins), converted with:

relinker --windows --module-dir Media/Modules --module-dir Media/Plugins eboot.elf app.exe

No environment variables. fakelib, dlc_emu.ini and DLC folders left out.

I used Claude to investigate this and write the report.
