Wobbly Life (PPSA29413) on Linux

Tested

• Title: Wobbly Life, PPSA29413 (UP7742-PPSA29413_00-WOBBLYLIFEEUUSXX), content version 01.160.000. Unity 2022.3.62f2, IL2CPP, FMOD, EOS (Epic Online Services plugins + vendored C# SDK), Rewired input, UMod arcade mods.
• Host: Linux x86-64 (CachyOS), Intel i5-12400, NVIDIA GeForce RTX 3060 Ti. Relinked with --registry --module-dir Media/Plugins --to-intel (--to-intel required: the title ships AMD-only insertq, fatal SIGILL on Intel otherwise).
• Last update: 2026-10-10

Status

Boots into arcade content streaming with rendering. Unity bootstrap, IL2CPP metadata, Addressables catalogs, FMOD banks (Master/Loading/PS5/Game), PSN/EOS/FMOD/burst plugins load with start arguments, GC stop-the-world via SIGUSR1 works, ~80+ shader-cache hits, 1920x1080 targets present. Import audit: 0 absent, 443 implemented, 19 stubs, 152 module-bound.

Open problem: one managed System.FormatException: "Unrecognized Guid format." deterministically ~60–90 s in, while streaming arcade bundles (right after resources.assets), terminating the run. Forensics so far: no missing files (extraction verified complete), no network sockets, no save/prefs I/O, no directory enumeration, no sceNpAuth ticket requests, Rewired (ControllerElementIdentifier, hardwareGuid/deviceInstanceGuid machinery) and game-code *GuidStr fields (jobs/mods/arcade: miningAreaGuidStr, ModGUIDComponent, …) adjacent in the managed heap, EOSSDK loads shortly before the crash window. The Guid input string is not stored in the exception object; caller not yet identified.

Still needed beyond main

Update: #1102, #1503, #1534, #1902 and #1928 have merged since. The local patch is 42 lines in one relinker file (#2212); everything else is unmodified upstream PRs.

Local patch: bind Linux guest imports by declared module identity

PR #2212 — full diff lives there. Summary: on Linux, executable imports shared between providers bind when exactly one provider's filename or SONAME is in the executable's DT_NEEDED list, and guest-module imports bind when the declared library resolves to one of the providers (the existing Windows-only filter now applies on both platforms). Anything else still throws exactly as before. 42-line change in core/relinker/relinker/src/guest/GuestModuleBuilder.cpp, no test changes needed (41/41 green, ambiguity regressions intact).

Notes

• Media/Plugins modules load with sceKernelLoadStartModule(path, 52, …); PSN loads ~6×, FMOD ~20×, EOSSDK 6× late in the run. SaveData/kitt/resonance/burst plugins never load before the crash. No EOS/PSN network sockets are ever opened.
• PS5Util (Unity) exports _Z5dummyv, arch_raise_user, arch_test, arch_init_gc, arch_DbgBacktraceSelf (+2 unknown NIDs); it imports _umtx_op, sceKernelSleep and 7 more libkernel NIDs.
• sysmoduleLoadModule unknown id: 267, 272 is tolerated (also seen on a working title).
• Unity 2022.3 managed Guid users validated present but not yet blamed: Rewired hardware/device guids, FMOD event GUIDs, UMod/mod *GuidStr fields, Localization TableReferenceFromString, game-code job/prefab Guid strings. The failing input string is not recoverable post-mortem (not stored in the exception object); sceKernelDebugWriteCppExceptionInfo receives what=nullptr.
• Worktree (detached, main untouched): main at a8b032b2 + the 9 PR heads above + the local patch. Temporary diagnostic patches (throw tracing, coredump heap probing, module-load/directory/auth logging) were all reverted; the tree diff besides the merges is only the submitted patch plus one test-expectation line for fix(libkernel): pass module args and argp to runtime-loaded modules on Linux #1102×fix(relinker): keep Linux imports declared from host modules off guest exports #1529 accessor imports.

Stack tried

main at a8b032b2 (2026-10-09), plus #846 + #1102 + #1503 + #1529 + #2051 + #1431 + #1534 + #1902 + #1928 and the submitted patch. Relinker suite 41/41. Deliberately not merged (checked, not needed or conflicting for this title): #755 (weak duplicates — both colliding exports here are global), #1482 (_umtx_op superset overlapping #2051; private ops unused so far), #1617 (closed, Windows-only owner binding), #2071/#1837 (other static-ABI misses; not hit), #2053 (HTILE clears; not hit). tools/nid_names.py + tools/import_audit.py for NID work.
