What is shown

Relinked with --to-intel, on main alone: logos, title, main menu, Episode Select and the opening cutscene of Sonic's episode, at 30 FPS, then the title stops with AGC graphics: non-finite register at DWORD 11 (a non-finite DB_DEPTH_CLEAR).

With #11998 and #12071: the same screens at 30 FPS, past the cutscene into the stage load, which stops with shader 0x201748200 stage 5: AGC driver: guest memory is not readable at 0x2d634b500 (range 0x2d634b500+0x4), as in #11469.

Relinked without --to-intel, on main alone: the title screen after 145 s, at about 2 FPS, because the AMD-only extrq/insertq instructions trap and are emulated on this Intel CPU. With #12071 the same build runs the intro at 30 FPS.

Input was sent with APS5_PAD_INPUT_FILE; audio was not checked.

Current blocker

• Stage load: AGC: a fragment shader's T# loaded through a runtime index inside an EXEC-guarded block is read on the CPU, so Sonic the Hedgehog (2006) Recompiled (PPSA99903) stops at "guest memory is not readable" #11469. Open pull requests linked there: fix(recompiler): defer the TYPE check of a guarded read-only static V# #6412 and fix(shader): poison an SRT read below a pointer loaded from memory #12208.
• In the stage, with local changes past AGC: a fragment shader's T# loaded through a runtime index inside an EXEC-guarded block is read on the CPU, so Sonic the Hedgehog (2006) Recompiled (PPSA99903) stops at "guest memory is not readable" #11469: stale geometry, AGC: Sonic the Hedgehog (2006) Recompiled (PPSA99903) draws its stage geometry with stale data unless draws or packet stores are synchronous #11562; fix(agc): hold small labels behind completions that store guest memory #11995 addresses it.
• Open pull requests the title needs before that point: fix(agc): accept a non-finite DB_DEPTH_CLEAR until a clear uses it #11998 (the stop after the cutscene) and perf(libc): fetch SSE4a instruction bytes directly within the faulting page #12071 (speed without --to-intel).

How it was run

relinker --windows --windows-gui --to-intel source/eboot.elf app.exe
relinker --windows --windows-gui source/eboot.elf app-sse4a.exe
APS5_PAD_INPUT_FILE=<file> app.exe
python tools/pad_input.py <file> options|cross

Nothing beyond the usage guide.
