• Title: Rise of the Ronin, PPSA04540, v01.009.000, dumped from the contributor's own console. The dump's eboot.bin and sce_module/{libc,libSceNpCppWebApi}.prx are fake-signed SELF containers whose segments are plaintext, so they were unwrapped to plain ELF before relinking. There is no decryption.
• Host: CachyOS (Linux 7.2.9), Ryzen 7 7800X3D, RX 9070 XT (RDNA4), RADV / Mesa 26.2.4. Runs are headless in gamescope with scripted input.

Status

Not in game. No frame has been presented yet.

Stack (on main)	Where it stops
main	Doesn't load: 13 imports are not exported (list below)
+ #2153 + throwing placeholders for the other imports	about 9 s: s_swappc_b64 call target at program counter 0x00000074 is not statically resolvable (#1817)
+ #1836 + #1837	no stop in 6 min; the main thread stays in Structurize → computePostDominators and gets through 1 to 6 registrations per 10 s
+ #2105	about 3 min 40 s: AGC driver: unsupported registered shader type
+ #1893	about 4 min 40 s: NGS2: system option flags are not implemented

Imports missing on main

• libSceUlt: _sceUltUlthreadRuntimeOptParamInitialize, _sceUltUlthreadRuntimeCreate, _sceUltUlthreadCreate, sceUltUlthreadTryJoin, sceUltUlthreadRuntimeDestroy. Covered by feat(libSceUlt): implement sceUltUlthreadTryJoin, sceUltUlthreadRuntimeDestroy and the underscore ulthread exports #2153. The title calls them during its first second.
• libSceJson2: sce::Json::Array::Array(const Array&), Array::clear, Array::front, Array::iterator::operator->, Parser::parse(Value&, int (*)(char&, void*), void*)
• libSceSaveData: sceSaveDataCancel
• libSceNgs2: sceNgs2ReportRegisterHandler, sceNgs2ReportUnregisterHandler
• libSceNet: sceNetShowNetstat
• libSceRazorCpu: sceRazorCpuPushMarker

The title called none of the libSceJson2, libSceSaveData, libSceNgs2 report, libSceNet or libSceRazorCpu functions above in the first 4 min 40 s.

Current stop: NGS2 system option flags

sceNgs2SystemCreate* gets an option with flags = 2, name KTSL2 (Koei Tecmo's sound library), 512/512 grain samples and 48000 Hz. CheckedSystemOption throws on any non-zero flag. I don't know what bit 1 means. If anyone has a reference for the NGS2 system option flags, that would settle it.

Update 2026-10-10: main b5f5362d3

Since the first post, #2153 (libSceUlt) and the shader work it needed (#1836, #1837, #2105, #1893, #2327) are all on main, and sceSaveDataCancel is now exported. The table above shrinks to:

Stack (on main b5f5362d3)	Where it stops
main	Doesn't load: 8 imports are not exported (list below)
+ throwing placeholders for those 8	about 30 s: NGS2: system option flags are not implemented

So on current main nothing but the missing imports stands between the title and the NGS2 option stop, which used to take 4 min 40 s and five open PRs to reach. The title did not call any of the 8 placeholders before that stop.

Still missing on main:

• libSceJson2: sce::Json::Array::Array(const Array&), Array::clear, Array::front, Array::iterator::operator->, Parser::parse(Value&, int (*)(char&, void*), void*)
• libSceNgs2: sceNgs2ReportRegisterHandler, sceNgs2ReportUnregisterHandler
• libSceNet: sceNetShowNetstat
• libSceRazorCpu: sceRazorCpuPushMarker

On the NGS2 option (flags = 2, name KTSL2): the only public reference I found is shadPS4's PS4 reimplementation, whose SystemSetup reads option->flags >> 31 alone (it selects how the context buffer is laid out) and passes no other bit into system setup (ngs2_impl.cpp). That does not say what bit 1 means, or whether the PS5 library uses it later during rendering, so I am leaving CheckedSystemOption as it is.
