Title

PS5CEMU-HAR (PPSA99360)

Content version tested

03.005.000 (PS5CEMU-HAR 3.5.0)

AnyPS5 commit

main 90c6839, relinked with --trap-sdk-syscall-stubs (#3804). The later runs stacked the open PRs below on main 2a5eca1: through #4469 on both systems; the /data and poll runs were on Linux only.

System tested

• Linux: Ubuntu 24.04, GCC 13.3, headless (SDL offscreen driver, no window)
• Windows: Windows 11 Pro 25H2 (26200.9457), RTX 3080 (NVIDIA 591.86), WinLibs GCC 15.2.0 r7, Release

What is shown

On main it doesn't load: undefined symbol: 5KWrg7-ZqvE (pthread_setaffinity_np) on Linux.

With the open import PRs below it loads and starts (PS5CEMU-HAR 3.5.0 starting (Cemu at 32e6628, Azahar at 4aef900), HEN: ok (already root); JIT available), then refuses to start its launcher:

[main] HEN: ok (already root); JIT available (the HEN's); /data unreachable, elevation helper: 9
[main] PS5CEMU-HAR cannot reach /data. Load a HEN with PPSA99360 in its app jailbreak list, or elfldr, then restart PS5CEMU-HAR.
[main] the launcher could not start or stopped drawing

With an empty data folder in the run directory it logs /data reachable and goes on to poll: descriptor 8 is not a socket.

Current blocker

Update 2026-10-14: none in AnyPS5. Its last open pull requests, #4514 (pthread_setaffinity_np), #4467 (swscanf) and #4469 (sys_siglist / sys_nsig), are merged. On plain main 9b6555b (Windows 11, RTX 3080, --trap-sdk-syscall-stubs) its launcher renders at 59.93 fps with Home / Library / Settings and the Wii U / 3DS switcher. It then waits for the user's Wii U games in /data/ps5cemu/games. On Linux headless it gets to the DisplayWindow throw.

How it was run

The catalog eboot.bin unwrapped and relinked with --trap-sdk-syscall-stubs (--windows on Windows), 30 to 60 s per run. The stack with the import PRs is test/verify-cemu3 on babyhuey/AnyPS5.

Update 2026-10-13, Windows 11 (RTX 3080, WinLibs GCC 15.2), --trap-sdk-syscall-stubs: with its whole open-PR chain stacked on main 495bf91, the launcher renders.

Stack (fork test/verify-cemu4, 6d2c67d): #4514 (pthread_setaffinity_np), #4467 (swscanf), #4469 (sys_siglist), #4690 (/data at start-up) and #4525 (POLLPRI under WSAPoll). Several conflict with main now; I merged them by hand, and it builds with no warnings.

[main] HEN: ok (already root); JIT available (the HEN's); /data reachable
[main] app folder /app0
[ui] the new launcher is up in 1158 ms
[ui] frames=2401 avg=16.68 ms max=17.18 ms
[ui] frames=3001 avg=16.68 ms max=17.27 ms draws=1 instances=1232 gpu=8 MiB

So it holds 60 fps in its launcher for the full 60 s with no throw. (An earlier run picked /data/homebrew/PPSA99360 as its app folder because our test harness left no eboot.bin in app0; with that fixed it uses /app0.)

Open pull requests it needs, unchanged: #4514, #4467, #4469, #4690, #4525. The poll stop listed before is covered by #3644 (merged) plus #4525. Starting a game hasn't been tried.

[babyhuey]

Update 2026-10-13: #4690 (/data at start-up) merged. Open pull requests it still needs, in order: #4514 (pthread_setaffinity_np), #4467 (swscanf), #4469 (sys_siglist), #4525 (POLLPRI under WSAPoll). On main c13dc7e it still stops at load on pthread_setaffinity_np.
